|I was having major rear tire wear, I was going through tires like oil.
Les Schwab said I had a bent spindle or that my rear axle beam was bent. I was like yeah OK how did that happen?
I have lifetime alignments at Firestone and my rear toe was the only thing that was way off. Toe specs for 337 or sport suspension are: rear toe specified range is -0.09 to 0.57.
My Actual was Left: -0.43, Right: -1.44
That is way off, Major tire wear.
I just got done installing the Energy Suspension rear axle beam bushings part# 15.3118r.
I did it without removing the rear beam from the car, I left the shocks hooked up, and took out the C-clips that hold the brake lines and one bolt on the passenger side that held a bracket up to the body, also unsnapped the lines from the plastic clips, I also unplugged the wheel sensor. I took out the rear bushing bolts and lowered the axle beam slowly and watched my brake lines so I didn't bend or pull on them. U might need to loosen the shock mounts a little bit, NOT all the way for some clearance.
I used a cold chisel to get the stock bushing out, and then a hacksaw to cut the sleeve and then some hammering with a flat-head and the sleeves came right out.
The poly bushings go in so much easier than the stock ones. Use enough silicone spray and they slide right in.
Bolt it back up, but don't tighten the bolts all the way till u have the wheels back on the ground.
I had to remove the shock mounts after I was all finished putting the poly's in to get the rear bolts to line up, One side went easy but the other side was a being mean
Put your clips back in the brake lines, bolt the bracket back up, and then plug back in the wheel sensor. Use a jack under the springs to bolt the shock mounts back up.
Put wheels back on lower the car and tighten the two bolts. ALL Done, time to relax
Then U Need an alignment.
I have already done the front control arms with the ECS Poly/Heavy Duty kit.
My car is so much smoother on the freeway and it hugs corners like a brand new car. My car is 8 years old almost 9.
