Rebuilding the front

jimny_IMG_20171110_185655

Having previously re-built the rear suspension it is time to sort the front. Again this is a KAP 3" lift with Pro-comp shocks and this is where the main "sag" is.

More goodies arrive!

Jimny_IMG_20171109_210355

As we all get older things sag at the front, just ask anyone over 50! My Jimny is heavy and my old springs have worn out. However when compared to the new springs the old ones are actually longer! This is more about turns and wire diameter. The new ones have an extra turn and are made of 13mm wire compared to 11mm so I believe they will hold up rather than just compress and sag like the old ones. I can actually press the old ones by hand!

Still, there is a lot of weight up front so I decided to give the springs a fighting chance.

New tyres

regal2250_IMG_20171106_155451
My new tyres arrived today. Maxxis Bighorn 235/85R16 which I put onto a set of Grand Vitara 16" Deep dish rims. Polish guy down the road popped them on for cash in hand. Looks like I might have to strengthen things in order to turn them :)

Corrected Rear Arms

If you look around the internet, there is a lot of advice and conversation around castor correction for the front radius arms following a spring lift. However there is a lot less discussed about rear axle correction. Clearly "castor correction" does not apply to the rear but there is still an adverse effect due to a spring lift. There are two main effects, the nose of the differential is at the wrong angle which increases the angles the propshaft has to cope with and the spring mounts are not aligned top and bottom resulting in "banana" springs.

Fitting rear bump stops

JimnyIMG_20171012_183031

The key to a good suspension set up is balance and stability. Over stretching in any direction achieves very little. Ok so the vehicle may seem to have amazing "articulation" but if the tyres are not generating traction (ie pressing on the ground) it does not matter how far they have stretched to touch the ground. Bump stops are a way of protecting the suspension from over compression on one side and the tyres from rubbing inside the wheel arch. Therefore, with a new set of springs and shock I also have gone for bump stop extensions
