2 x BMW Z4 E85/Z4M E86 Rear Subframe Front PSB Poly Polyurethane Bushing Kit 2003 -2009 (Part No. PSB651)
PSB specializes in manufacturing polyurethane “problem solving bushings”. We strive to develop new and innovative products that are not just factory replacement parts, but actually solve many complex and inherent design problems in new vehicle suspensions.
Two Reasons Our Bushings Are Successful:
Design – The sleeves in our bushings freely rotate which enhances longevity.
Installation – Once removal of original bushings has taken place, installation of the new polyurethane bush typically takes from 1 – 5 minutes to install, the techs love it!
Why use Polyurethane?
Polyurethane bushings are stronger and last longer than standard rubber bushings. Most modern production vehicles are designed using rubber bushings which have a limited lifespan. This contributes to suspension failure due to vehicular weight and the inherent design of high-tech suspensions. Typically this results in less than desirable vehicle handling and can cause many related parts to wear out more rapidly than necessary. Polyurethane corrects this problem and in many cases improves vehicle handling and drivability.
– This product is manufactured with the highest grade of polyurethane and the durometer of the bushing is designed to fit the application.
– The quality and lifespan of this product far exceeds the original part.
– If this product does not meet with your expectations, we will refund the purchase price if returned within two weeks after the purchase date.
1. Remove worn OE bushing by pressing out or using a blow torch.
2. Ensure outer metal casing of original rubber bushing is removed, which can be done by cutting with a hacksaw and knocking out with a chisel.
3. Clean housing with sand paper to remove sharp edges, so as not to damage new bushing.
4. Remove metal sleeve from new poly bushing.
5. Lubricate inside and outside of new poly bushing with multi-purpose grease.
6. Press new bushing into the arm, ensure the most tapered flange faces the arm when pressing in the new poly bushing.
7. Bench vice or mechanical press can be used.
8. Once the bushing is inserted. tap the metal sleeve into the bushing, using a rubber mallet.
9. The new bushing installation is now complete.
