I'm planning out my rear suspension rebuild, and I'm leaning towards using spherical rod ended parts for everything - LCAs, track bar, and torque arm. Has anyone done this on a street driven car? I'm wondering how much it will increase road vibration being transmitted to the car body.

 

I have a rod-ended UMI Performance Panhard Bar, ans am on 17" tires, so shorter sidewalls than your 16" tires.

I noticed NO increased vibration or noise. Double rod-ended rear LCAs are next on my list.

 

You won't have much affect at first, but you'll have to replace the rod ends, and that can get expensive.

 

I didn't notice much but then again I did sportlines at the same time so the car was bumpy as hell until I put new struts/shocks on it. Noise didn't get bad until this last year. The LCAs are still good but the panhard bar rattles a bit because the rod ends are loose. That's about 4 years of street driving. A bit over 100k.

 

Good rodends that will hold up to daily use for 3 years "without" problems will cost you close to $100 each.

I mean zero problem rodeneds, not ones that have a little slop.

 

That's why I think I'm going to replace my worn rod ends with the rubber ends I have on the body ends of my LCAs.




I can swing ~$100 for all alot easier than ~$300+.
