So I have everything out in the rear of my car except the trailing arms. One moves up and down with ease, the other is quite tight and requires pressure to move. Both bushes are rubber and in good condition. Should I loosen the tight one or tighten the loose one? Any rubber lubricant needed here? Just how tight should they both be?
Bill, the original trailing arm rubber bushes, like the front ones, were torsion bushings. That is there is not suppose to be any slippage of the bushing on the bolt or in the trailing arm. The rubber itself flexes allowing the trailing arm to rotate, so no lubricant should be used.
The trailing arm bushings should be tightened only after the car is on the ground, and the suspension settled. (Or guesstimate it's position.) Otherwise you stand the chance of over flexing the rubber and it will tear.
If that loose bushing does not tighten, it is probably damaged, and all four need replacing.
