I installed new control arm bushings several years back, but it has taken a while to get the car on the road. Right now those bushings probably have less than 5 miles on them and they are split and falling apart! This was noticed when I took it to the vette shop for an alignment. These were Rubber bushings from Moog (I believe it was, they came in the package with the shafts...blue and white box). Is it possible these were just old stock and rotted to begin with? Or is there another problem I should be looking for that could cause this? Car is a 78 and suspension set-up is stock other than a spreader bar. Shop is going to replace them with poly bushings for me, but I want to make sure we arent missing something else.

Seems like you got a cheap replication part boxed in a Moog Box. I would question the place that sold the part. New rubber should be good for many years.

Now for poly, do a search here you will find similar problem with poly bushings falling apart in 1-2 years also.

I have poly everywhere, expect a harsher ride. They have been installed for 3 years with no sign of failure or aging.

They are made by energy suspension.

A Few of the "black" polyurethane components contain graphite to add a lubrication property check if the bushing contain this.

If they don't they will start to sweak at some point.

To the best of my knowledge, genuine Moog parts come in YELLOW and blue boxes......

If you bought them over the internet, they are probably junk phonies.

That is a bummer to redo..

all my Moog stuff is in yellow & blue Moog boxes

hmm...it has been about 5 years, so i could be wrong on either part of that equation! I cant seem to find the receipt.

Thanks Richard, at least it seems as it is not an uncommon problem. Im not sure if that is a good thing or a bad thing though. This shop said they have good success with these poly bushings, so i will give them a try.

Vette-kid

yes it is! Not a fun job at all!

Also......just hand tighten the bolts that hold the control arm bushings in place......then lower the wheels onto the concrete/roll the car forward and backward a few feet to let the control arms and tires "settle".......then while the car is on the concrete tighten the bolts to the correct torque (this method prevents the rubber inside the bushings from "twisting to pieces".

Found an old pic...not sure if the top was yellow but this view is white

x2!

Like rubber but dont trust its origins these days. Curious to see how long the body mounts (rubber) hold up

What a pain....get the polygraphite (black) never had a squeak or anything looking funny

Hi DG, rookies don't know this kind of stuff. As always good advice from you. T

Imported from Mexico, not real USA Moog.

Vette-kid

hmm...so is this a "fake"? At any rate Im not using those again!

Vette-kid

Thanks for the tip! I wish I would have known that back when I put them in! Live and learn

Ill let the shop do it this time around since we have a baby due within the next 2 weeks or so...no time for this type of thing right now. Stink to have done it and have to pay someone to do it again though.

I learned it from Forum members...........

and here's an early CONGRATS!!!

Problem is, Moog, as well as way too many American manufacturing companies, is moving more and more of their operations "off shore". I learned this by working part time at Advance Auto Parts, after retiring from full time work.......


Thanks, EPA and OSHA!!!

Absolutely!
This is the sort of thing that is common, and should be included in the instructions.. but it's not.

It's in the service manual. Good book to have when working on these cars.
