I am back! Liking truck more and more, just keeping driving it and forgot that suspension need attention. Not really, but it rode OK-ish so I kept riding it. Well, it got to the point where I can't tolerate clunks anymore (front axles, front diff), leaking steering rack (AT205 worked for couple K miles) now I have drips. Time to work on it.
But I like to find myself "projects" and knowing if I take care of front - will not get to rear end. Thats why starting with rear end suspension and once done - will move on and finish upfront.
I had new bushings and other pieces purchased long time ago. Started with creating bushings to use with a press. For panhard bar - deep socket worked (I think 27mm?)
For upper/lower arms I had to A. Modify old chinease socket(turn it down with a step) and make another small washer for bigger bushing.
Yes. With press and precisely made to size tools - those bushes there tight! RTAB bushings in E34 BMW were even worse, but those bushings in LC100 rear end is my solid #2. Panhard bar was first and it went pretty easy so I thought it's no biggie. Arms though were not so easy. However! I came up with a trick, maybe not a trick for seasonal mechanics but it worked wonder. I took propane torch and heated arms around bushing - started to go much easier! Those OE bushes painted or have some kind of plastic around which kind of glues them in. With heat - you melt it and it becomes a "lube". I would not attempt those bushes without a press..
Verdict: Upper arm bushes - shot completely
Lower control arms bushes - pretty bad. I forgot to check orientation and position of directional bushing, will do with 2nd arm. But it's interesting! LC100 uses 2 different kinds, one solid and one directional. I will be installing both directional bushes from LC80.
Dilemma:
A. Put new bushes, put it back together and most likely I won't need to touch it ever (rear suspension)
B. Take down rear diff, it's almost out. Remove shocks and replace shock rubbers (AHC). Cleanup around, treat with POR15 in spots. Rebuild rear calipers, rebuild/check parking brakes.
Most practical will be to go with A but perfectionist tells me to do B. Decisions, decisions..
