I bought a complete set from Kanter. Including new springs and shocks. The shocks was stupidly designed as the threading was to short on upper rear shocks, but after har labor when fitting it all was great. Also have replaced rear bushings and ball joint. Its worth buying the new stuff.
Suggest you wait for Russ new control arm. I think I would go that route if the price is acceptable. Do remember that the cost of replacing the rear lower control arm bushings is at least 150 USD.
The rear bushings are at 80 each x4 The cost of the new control arms are looking to be in the 375 range.
375 USD for a new control arm with better bushings sounds reasonable. 650 USD for a set of 2? Not that anybody will buy one...
I noticed that the bushings were reproductions. If original MOOG parts could be found, it would probably give the same ride quality as the new control arms.
The point of the whole endeavor is that the reproduction bushings are junk and do not last even a few years.
Urethane is a proven performer and will last a very long time.
Tony, the stock bushings are encased in a metal sleeve, that gets pressed into the control arms.
There is a way to put custom made bushings into the stock arms. The old bushing needs to be pressed out. Then the rubber is burned out of the shell. Custom bushings are machined to fit into the shell, and a sleeve is made for the bolt to pass through.
That is a slow and not very efficient process. A customer would need to send in his old bushings and wait for the new modified bushings to return.
It is quicker and easier to just bolt up a new set of control arms.
As far as structural integrity, a box is stronger than a U shape. The stock control arms are U shaped.
The ride is not rear end bouncy anymore. I still have the Cadillac ride, but now it is much better. The movement came from the bushing having movement, causing the axle to rotate, affecting the shock and springs.
This is absolutely one of the best mods I have done to the car. Disk brakes, AC, and the rear control arm mod.
If the purist wants the original look, then getting custom bushings made is the way to go. I wont offer that service, so a trip to a local machine/fab shop would be in order.
Hi Mack, I realize this post is old but let me know if you still need front suspension parts. I have a set of PST (Performance Suspension Technology) ball joints and bushings - complete set for the front end.
