Eibach lowering spring problems

Sorry to post two times the same topic!

I just installed mi eibach pro kit lowered (1' front, 2' rear) on my wk2 2012.



I have stock wheels, stock tires (265/60/18),

stock everything.



I have balanced my wheels, throw in an alignment with negative camber for front wheels and rear wheels (because of the lowering) its negative 1 on all four of them.



Everything looks good but when im on the highway making 60mph the steering wheel starts to shake, its controllable but its annoying on long trips.

When im above 70 mph the shakes does away.



I have checked the tire pressure and they are ok. The only thing I have on my mind is maybe the tires. They are old (the ones that came with the jeep when i bought it new) or the control arm bushings.



If you know what part I have to look for play on the control arms or the steering components please tell me, im going insane!



Thanks!

Re: Eibach lowering spring problems

Did you replace the shocks at the same time? If you didn't it may be part of your problem. But I always thought that vibrations at certain speeds could be attributed to tires or balancing

Re: Eibach lowering spring problems

Yes, I replaced all the springs at the same time. I have read that I need a hub centric ring, maybe thats the thing im missing

I asked if you replaced the shocks. Unless you are running some sort of non-Jeep style replica wheel I wouldn't think you would need hubcentric rings. They are typically for an aftermarket wheel that does not have the same size hub as your Jeep.

Re: Eibach lowering spring problems

I replaced the shocks before the eibach springs. I have the stock oem 18 wheels that came with the limited but my car is a laredo. I dont know if that matters.

Eibach lowering spring problems

Shocks and springs should be paired. There is a calculation of spring rate, shock compression and rebound as well as tire circumference that equals nice driving feel.
When I do mine I'll do Old Man EMU for that reason

Re: Eibach lowering spring problems

Have you checked the upper control arms for play......?
They are known to wear early.....

Re: Eibach lowering spring problems

FIXED

Good new everyone!!! Using stock wheels, I jacked up the car on both side (left and right) and torque the wheels above the ground, first 40, then 80, finally 100.

I found that the wheel hub has .6mm less than the center bore of stock wheels. So the acorn lug nuts help centering the wheel, but it has to be in stands or jacked up at the same time.

Also I rotated the tires

Im so glad I found this solution besides buying new bushings or new tires.

Problem fixed!
