IRO rear control arms.

I have a complete 4.5 inch IRO lift. Have about 15k on it . Now it wanders all over after feeling like it comes from the rear.
I visually inspected the rear suspension and it looks like the lower rear control arm bushings ar bulging out . I know they didnt look like that when I installed them.
Could that cause my wandering issue. It happens at all speeds and conditions. Worse on the freeway or during turns or acceleration or braking.

Thanks

The WJ rear axle is prone to axle steer when the control arm bushings get worn out. That sounds like the likely culprit. Have you been doing a lot of offroading?

Well good thing I already have a set of new adjustable ones from IRO that I havent had time to swap in yet. Ordered from you Kolak in the spring.
I've been doing a moderate amount of wheeling and towing my tent trailer as well as pulling stuck cars out of snow for the last few winters.
I'll start their and see what happens...

Thanks.

I dont think they are supposed to look like this. Did I forget to put a spacer washer in. They fronts and lowers have the large hardened washers as well.

That doesn’t look like an IRO rear control arm. Is it? You say you have new adjustable arms ready to go in so those must not be.

Yes the IRO rear lower adjustable arms have significant spacer washers.

I agree. Just replaced the rear LCA with IRO parts for my 4" lift (via Kolak) and they should have spacers to get the right offset.

I think the universe is telling you it's time to install the adjustable arms
