How to do

During the disc brake service it became obvious: The swivel link bushes are ready for renewing. After thinking it over, the decision was to do it myself - why always the workshop should have all the fun plus being paid for it ;-)

At first the necessary parts were ordered: Bushing, steel tube, thrust washers and rubber parts. The pieces are quite cheap, a set for around 20 DEM (10 USD).

Next step was to get some know how. How to extract the old bushes and how to press in the new bishes? Is it possible with the means of a "shadowtree mechanic"? The internet was quite helpful - there were to main groups of answers, the one recommend to let it with a workshop, the other group told it could be possible - with the means of pure and brutal force. The latter route sounded more interesting...

The tool box was filled with a trolley jack, jack stand (used as a "special tool"), puller, adjustable reamer, hammer (10 pounds), 1/2 inch socket, 1/2 inch socket extension...and the usual things.

At first, the standard program: Jacking up the car under a spring pan, removing front wheel, removing brake caliper, removing front hub. Then it is possible to remove BOTH swivel links (without removing the hub it is not possible to remove the lower swivel link). A good opportunity to clean the front suspension, by the way!

Now comes the interesting part of the work: Using the jack stand as mounting device for the swivel link, the 1/2 socket plus extension is the perfect drift. Within a few seconds, the old bush is pushed out. The new bush is pressed in with a solid vice. The old thrust washer helps to prevent any damages.

With the adjustable reamer, we have taken our time. We found out the best way is to use the reamer in 4-5 increments to create a tight fitting for the steel tube. Assembling is the reverse procedure...dont forget to use the grease gun...et voila!

No comment.

 

Old bush will be pushed out - no mercy!

 

Pressing in of the new bush...

 

...every little helps ;-)

 

Reaming the bush - exact bore is 0.750 inch.

 

Alls well that ends well - the overhauled swivel link.
