How long do thrust arms and bushings last?

[Sam-Son]

My thrust arms were replaced not 5000 miles ago and already I'm getting that horrid shimmy in the 50-60 mph range. What's going on? Any Ideas?
Thanks

Hub-Centric rings????????????????????????????????
Should be longer than that,Suggest you look elsewhere, hence my comment.

Originally I had crappy spacers which I thought was the source of the problem the first time but after looking through the bentley book I found out it wa the thrust arms, replaced them and the problem went away. and I replaced the crappy spacers with Eibach spacers from Bavauto. Now the problem's back I kinda doubt it's the spacers because they're of rather high quality. Any other ideas maybe some how the wheel is out of balance?

Did you buy lemfoerder parts, or cheapo ones? If you buy the cheapo ones expect them to wear out every 6 months.

Did you do the lower control arms at the same time? They cause just as many problems.

Were the control arm/bushings changed at the same time? Have your wheels been dynamically balanced? Nice looking car, by the way!

did you torque the bushes under load like on some ramps? id say lower bushes last 220,000+kms and the upper ones, 100,000kms+ depending on the type.

NOT LONG ENOUGH GRRRR!

I would also point to improper installation. Even the cheesiest should go more than 5k.
If the bushing through bolt is tightened with the suspension hanging it is always under load. Loosening and retightening the bolt with the car on the ground might relieve it a bit.

seen blue ones crap out and start shimmeying in 3 months, seen green ones crap in 6, m5's are the way to go, if it shimmeys with m5's A, your rotors are warped or B, your running ungodly heavy wheels C, your wheels are square/way outta balance (seen a wheel with 15oz of weight on it where they didn't know dick about using a balancer, i am waiting to find the holy grail of ****tard balancer, a full pound of weight on a car tire)

I haven't tore up my M5 bushings yet, the stockers and 750 bushings I can tear up in less than a day if I'm testing things
