If you off-road a Jimny (or any of the Suzuki classic 4wd vehicles) then you may well end up changing a CV Joint. These are a weak point in the front axle and will break if you are heavy footed or have large tyres fitted.

of the steps are duplicated.
 
So what are the symptoms of worn Wheel bearings:
 
* Grating/Grinding as you rotate a jacked up wheel
 
* Steering Shimmy, see [[Death_Wobble | Death Wobble ]]
 
* Oil/Grease leaking from Swivel Joint
 
* Horizontal play in the front wheel (with the car jacked up grip the wheel sides, there will be movement if they are worn. Get an assistant to press the brakes and the movement should disappear)

* Type 2: 8 balls, 26 external splines and 29 internal splines. - Difficult to source, 6 Ball Jakoparts J2828040 is supposed to fit.
  
It is also common not to experience any play at all and to even pass an MOT with a really bad bearing. This is because the bearings are dual race and only one race may have failed.

Note: I can get Type 1 for you, I just do not stock it as too many people bought the wrong one and wanted to return it.

With the hub removed the driveshaft is exposed. The driveshaft is retained with a circlip so use a pair of circlip pliers to remove it. This is really fiddly and can be an annoying task.

[[File:vacuumpipe.jpg|thumb|250px|left|removing a vacuum pipe]]
Now for the special tool. The hub is held on by a special round nut that requires a special tool to release it. The outside of the nut is a smooth polished ring which is part of the vacuum seal so it must not be damaged otherwise you will need a new nut(which is exceedingly expensive!). In the centre of the nut, the edge is bent over into a slot to help secure it, the slot can be seen in the above photo in the “2 o’clock” position, use a blade to bend the edge back into line. It is essential that this is completely free otherwise it is impossible to undo the nut and you will break the tool.
+
Gently pull the two vacuum hoses for the hub from the knuckle making sure you note which one connects to each pipe. It is essential that you get this correct else the hub will not work again. Also note that if you have an ABS equipped vehicle then you will have to remove the sensor. I do not have photos of this but the video shows it. IT IS REALLY EASY TO SHEAR THE ABS BOLT - if you can I would soak it for a couple of days previously in penetrating oil.

This is the tool, it is available from the [https://www.bigjimny.com/store/hub-nut-tool-suzuki-jimny.html BigJimny Store]. Make sure that the tool and the nut are completely clean as the tool will not fit. Make sure the tool is inserted into the nut correctly with the pins all in the holes in the nut, you are really going to have to swing on the nut to release it. I had to use a long breaker bar AND a piece of scaffold tube. With the nut removed the hub should be removeable, it might need a pull with a slide hammer, mine just pulled off by hand.
+
At the rear of the hub release the small bolts holding the seal and retainer. You can see that the swivel hub is covered in oil, a bad sign for KingPin problems.

Then you can use a pair of long nose pliers to remove the C-Clips that retain the bearing, note that these may be corroded in and difficult to even see at first.
+
Finally, release the KingPin bolts themselves. There are two sets, top and bottom and they must not be mixed up so you can see in the picture that I have marked them up with a letter T. If you are doing both sides at once then do not mix them across either!.

The KingPins are also held in with sticky sealant so you will need to prise them out. The hub will now pull off. Beware, if they are badly worn the hub will be full of stinking grease, oil and water so make sure you can capture the mess in something. This is the bit I hate because of the smell!.
Now comes the first bit that is supposed to be difficult. Suzuki say that the bearing needs to be removed using a press. I decided to have a go myself. Using an old piece of bearing and a steel pin I hammered out the bearing and it only took two or three swift blows. The picture shows the steel pin resting on the bearing before being hit. Note the use of the brake disk to provide a holder for the hub allowing the bearing to be driven out of the bottom.

Changing the CV joint

Introduction

If you off-road a Jimny (or any of the Suzuki classic 4wd vehicles) then you may well end up changing a CV Joint. These are a weak point in the front axle and will break if you are heavy footed or have large tyres fitted.

It is also closely tied in with changing/working on the kingpin bearings so some of the steps are duplicated.

So what are the symptoms of worn/broken CV joints:

  • Clicking when in 4WD when turning
  • Banging and snatching of the steering wheel
  • Loss of 4wd

CV joint information

Suzuki uses two different CV joints in the Jimny. One is straight forward to purchase on the parts market and the other is nearly impossible to source.

  • Type 1: 6 balls, 26 external splines and 19 internal splines. - Easy to source
  • Type 2: 8 balls, 26 external splines and 29 internal splines. - Difficult to source, 6 Ball Jakoparts J2828040 is supposed to fit.

Note: I can get Type 1 for you, I just do not stock it as too many people bought the wrong one and wanted to return it.


Changing the CV joint

Tools

Spanner Icon.png
  • Standard metric sockets and spanners
  • Assorted screwdrivers
  • Circlip pliers (External)
  • An E10 Torx socket for the Vacuum Hub Bolts
  • A ball joint splitter
  • 1" Imperial Socket
  • G-Clamp or brake piston retractor



The Video

Before you read the guide below you may wish to view the video. This shows the changing of the Kingpin Bearings on a Jimny fitted with ABS so you will see me remove the sensor etc.

The rest of the guide below shows the same task in a series of steps for clarity

Removing the Caliper and pads

Jimny Front Caliper

First of all secure the car, release the wheel nuts and jack up the car and remove the road wheel. This then reveals the brake caliper, this is the passenger side (nearside) caliper (UK)

Unbolting the caliper

Using a 12mm spanner, release the front caliper bolt (the left is the front of the car in this picture) and loosen the same bolt on the rear of the caliper.

Open brake caliper

The caliper then opens up using the rear bolt as a hinge.

Removing the brake pads

The pads are retained by small spring clips, a simple pull on the pads (horizontally away from the disk) should remove them (or gently prise out the pads with a small screwdriver - do not remove the spring clips). If you require new pads, spring clips or a caliper fitting kit then these are available in the BigJimny Store.

Removing the Brake Disc

Carrier bolt

The caliper is held on with two bolts at the rear (see below).

Caliper tied to Spring

Release the bolts and tie the caliper to the spring to keep it out of the way.

Disc removal using bolt

Now the front brake disc can be removed. If you are lucky it will simply pull off but if you have problems then there are two M8 holes in the disk hub. Simply run two bolts into these holes and the disk will push off the hub. The picture below shows a bolt being used to push the disk off the hub.

My disk appeared to be ok on the visible side but the rear showed some bad wear so I will change them as part of this job. New disks are available in the BigJimny Store.


Dismantling the Hub

Torx bolt on hub

Now the Freewheeling Hub needs to be removed. Suzuki have used Torx bolts to secure these so you will require an E10 socket to remove the bolts.

Removing the circlip

With the hub removed the driveshaft is exposed. The driveshaft is retained with a circlip so use a pair of circlip pliers to remove it. This is really fiddly and can be an annoying task. Behind the circlip is a rectangular washer that should also be removed. Note that I have also marked with white paint the orientation of the freewheeling hub, this is not strictly needed.

removing a vacuum pipe

Gently pull the two vacuum hoses for the hub from the knuckle making sure you note which one connects to each pipe. It is essential that you get this correct else the hub will not work again. Also note that if you have an ABS equipped vehicle then you will have to remove the sensor. I do not have photos of this but the video shows it. IT IS REALLY EASY TO SHEAR THE ABS BOLT - if you can I would soak it for a couple of days previously in penetrating oil.

Removing the swivel seal bolts

At the rear of the hub release the small bolts holding the seal and retainer. You can see that the swivel hub is covered in oil, a bad sign for KingPin problems.

Splitting the ball joint

Undo the nuts on the steering joints, if the joint rotates then put a jack under the joint and lift the car slightly to lock the joint. Using a splitter, split the steering joints (two to do on the passenger side and one on the drivers side – UK).

undoing the Kingpin bolts

Finally, release the KingPin bolts themselves. There are two sets, top and bottom and they must not be mixed up so you can see in the picture that I have marked them up with a letter T. If you are doing both sides at once then do not mix them across either!.
The KingPins are also held in with sticky sealant so you will need to prise them out. The hub will now pull off. Beware, if they are badly worn the hub will be full of stinking grease, oil and water so make sure you can capture the mess in something. This is the bit I hate because of the smell!. That’s water pouring out of the axle! Also shown is a worn out bearing.


The bearings are Koyo brand as standard. The BigJimny store has two kits available, the basic kit has the two bearings and the small oil seal required to do one side. The full kit also included the large external seal although some people choose not to change this. The thing to remember is that it is not a Landrover which has oil filled swivels. The joints on Jimnys should be "dry" apart from some lubricating grease.

The next stage is to CLEAN, CLEAN and then CLEAN again. Clean the swivels inside and out, clean the knuckles and pull out the drive shaft and clean that as well.

The rebuild

The old bearing race

Once clean you can start the rebuild process. The KingPin bearings come in two parts, the race and an outer ring. This ring is still in the swivel and needs driving out.

Removing the bearing race

A simple way to drive them out is to use a 1" Imperial socket. Using an extension bar fed through the swivel place the 1" Socket behind the ring and drive it out by hitting it. (picture from Dave at Bits4Vits

The new rings can then be driven into place with a piece of wood to protect them from the hammer, again this is seen in the video (picture needed here).

I also hooked out the small axle shaft oil seal and put a new one in from the BigJimny kit. (picture needed here).

The rebuilt swivel

Here is the completed swivel with new rings and oil seal (and plenty of copper grease to help them all into place.
If you are changing the large seal then now is the time to put the new one on. The confusing part is the order of the seals and rings on the swivel, the picture below is of the correct orientation, note also that the slits in the retainers go to the top.


The greased CV joint

Pack the CV with grease (but do not overpack) and re-fit the driveshaft. A suitable waterproof grease is available in the BigJimny Shop.

Applying sealant

Grease the new KingPin bearings and insert the top one in the carrier. I find the easiest way to grease the bearings is to put them in a polythene bag with some grease and use thebag to squeeze the grease into the bearing, this can be seen in the video. (picture needed here) .Carefully insert the new bottom bearing and, holding it in place, slide the whole knuckle onto the hub. Fill the Knuckle with 100ml of grease, Suzuki recommend only 100ml and not to overfill. Now the KingPins need to be inserted, but first they need a bead of sealant around the KingPin. Again the BigJimny shop sells suitable sealant.
Make sure that you have put the correct Kingpin in place, remember you should have marked them when you dismantled it!

Bolt the Kingpins in and tighten them to the correct torque (18ft/lbs)

Refit the steering arm (or arms if it is the side with two connections), tightening the nuts to 31ft/lbs


Fit the disk and fit the caliper (Caliper bolts 61ft/lbs), brake pads and bolt the caliper down in position (Caliper pin bolt 16/ft/lbs)

Re-fit the wheel and lower the vehicle.

Torque Settings

Full details of the torque settings can be found in the reference data
