Liftkit and death wobble

Thank you very much!

Currently on standard wheel/tyre set and the car runs smoothly with no wobble at all.

Will go for a re-balancing of the aftermarket set.

26psi all round. Ideally you want lower that with a bigger tire although the tpms limits that on newer jimnys.

Good work Lars, it looks like the lift kit isn’t to blame.

Apart from balance (most likely the problem) check tyre pressure and make sure they are the same.

Whilst jacked spin the wheels by hand and check for flat spots or un-even rotation.

I have even heard that a layer of grease between the hub and wheel can stop the wheel siting square on the hub, if it’s bad enough to cause a speed wobble it should be obvious even with a spin by hand.

Good luck and keep us updated.

When the wheels are put back on check they fit square on to the hubs

I have a set of 205.70 renegade at5 that are proving to be something of a test for the 2 places I have tried to get them balanced by. That said I think it's an element of being too busy to do it precisely on the part of the second place insofar as 10g either side is close enough when on a live axle it actually needs to be nearer than that. Although it's worth mentioning that in some cases the wheels need to be bolted on via the studs rather than the centre bore but getting a place to do that is an uphill battle.

I had issues with my heavy 235 BFG MT's and balancing for a while but they seem to have settled now the last few years. I have no idea why this was an issue earlier but since balancing them the third time they have been ok.
I mentioned to the tyre shop that the original alloys center could be off, but i think they just spun them up and checked and reseated and redid the balancing thouroughly and that helped. Better to pay extra the first time for a good helping than to pay several times for next to no help.

Thank you very much!

So, a short update. Today the authorized Suzuki garage went through the car and (as expected) all bushings, bearings etc are in new and good condition.

Then went to the offroad company who installed the liftkit and the 15x7 and 235/75/15 wheelset. They have upgraded quite a few Jimny’s with the exact same package without issues. However they have used 15x6 rims rather than 7”.

So, to rule out that a 235 tyre on a 7” wide rim is to much, they will now mount the 235 tyres on my standard 5,5” wide steelies and see which result that brings.

I beleive that many use 15x7 rims, so doubtfull whether this is why the problem occured. More likely that balancing has not been done correctly or that wheels have not been sitting dead center on the axle.

A question: is it unwise to mount 235’s on a 5,5” wide wheel?

Will keep you updated.
