Hey everyone,
Just had to do some service to the rear end of my 88' 745. The large, oblong/odd shaped rear torque rod/arm bushings gave me some trouble at first, then I found a nice way to install these. The following information should apply to any 7xx/9xx series car with live/solid rear axle.
Using the AutoZone ball joint u-joint service kit I was able to install these bushing quite easily. I'm sure there are other tricks and that out there but I could not find any information about these and thought I would write this.
Pressing them out is not too bad. On installing, after destroying one of my bushings, I first pressed the bushing into the 2.75" ID receiving tube in the press kit with the aid of some silicone lubericant. (I tried dish soap on my first failed attempt and the silicone lube seemed to work much better for me, but maybe someone can weigh in here) After that it was really just a matter of finding the correct pieces in the kit and my own tools to press the bushing into the torque arm. Really didn't have to use that much force at all and the bushing didn't seem to deform much during installation.
Another note to mention is the positioning of the voids of the bushing in relation to the torque rod. After lining everything up perfect the bushing rotated by the time it was pressed in. To resolve this I put a suitable bolt through the bushing, tightened it up fairly tight, and was then able to easily rotate the bushing to the correct position with a a wrench. (I used the nut and bolt from the front strut rod I had around)
Hope this maybe helps someone and if I need to clear anything up or if more information is needed please let me know eh.
