JB74 Rattling noise driving me crazy.

Hi guys,

Wanted to check if any of you have had a similar experience , I have a 2020 Jb74 , OME lift kit with 235/75/15 tyres and stock rims.

I have an annoying  ratling noise in teh back that has been increasing in the last few weeks and after checking all the possible causes , I have narrowed it down to the spare wheel/wheel mount , don't know if it's the mount tha's deffective or if the tyre is too big and heavy or what the heck is going on but it's driving me crazy for sure , everytime I drive on uneven surface or bumps it rattles and it's very annnoying.

After checking everything in the back I decided to remove the tyre and w/o the tyre it doesn't rattle at all , I don't have the lightest tyre @37lbs but i know guys that have tyres heavier than mine and with bike racks,loads etc and have 0 issues.

Just wanted to check if any of you guys had a similar experience and how did you resolve it.

Thanks in advance.

Welcome to the forum. When you took the spare off I assume you did a spanner check of the bolts holding the carrier to the door and everything was tight? Also it might be worth popping the door trim off the inside and checking for anything obvious like a fatigue crack?

Do you still have the standard spare wheel cover on? If you have removed it, it could be the small bracket that it fixes to as it fits between the spare wheel holder and spare wheel. I think the wheel cover pulls it tight when the nut is done up.

It's a bit early in its life, but heavier tyres on the door affect the hinges and door lock.

I suggest you put the wheel/tyre back on and then manually rock the wheel/tyre to try and narrow the noise down. if still not sure remove door trim and see if that helps. A stethoscope could be very useful.

Mine didn't come with a cover.
 

Did you find out what the noise is? Mine is doing the same, 215 ko2 brand new jimny 2000 km on clock. Without the tire it does not sound but with the tire mounted even when I close the rear door I can hear the rattle. I have narrowed it down to either the closing mechanisms or the pillar where the seat belt is.

Anyone else with this rattle? I know of other 3 local Jimnys with same noise.

You all have my sympathy as a rattle can be annoying and drive you mad trying to locate.
Not G4 specific, but I have just found the annoying suspension knock and rear door rattle on my G3. The suspension knock was the wheel brace I had place in the rear jack storage area. The rear door rattle that I had narrowed down to the door latch / Pilar was the exhaust hitting the towbar!!!
I had convinced myself it was the door latch, but weight in the rear made it worse, so I kept looking as I did not understand why.
It's interesting that from the driving position the noise in both cases appeared to emanate from totally different locations to that eventually identified as the source..
I had to sit in the rear of the Jimmy whilst the wife travelled over the favourite rattle roads, even then it was not 100% clear as to the source.
So may be worth being a passenger and try to expand the possible causes.
Good luck.

l've not had this on our Jimny but have had a similar rattle on the Defender.
Try some oil on the rear door hinges and check the door catch, put some grease on the catch and see if it stops the rattle.

Hey epc2, I am experiencing the same issue with 215/75/15 tyres. Did you manage to find out what was causing the rattle?

The O/P has not been back since.

Looks like another Jimny owner who joined, asked a question about their car, got their reply and then disappeared never to return.
