I've started to notice a light "clunk" when accelerating from a complete stop or when getting on the gas from a slower speed. I did some searching around in the forum and saw that people tend to attribute the clunk to either bad motor mounts or bad trailing arm bushings. I checked to see if my engine jumps up when I gas it in gear and there doesn't seem to be a big movement in either the engine or transfer case shifter. I did, however, get under the pathy to check the rear arms and the bushings look pretty typical for what I imagine a 20 year old truck would look like. I am able to grab the control arm in the middle and twist it fairly easily like I'm twisting the throttle on a motorcycle. How much twist would be common with new bushings? I'm curious if my current bushings are within normal spec because I don't seem to get much wobble or instability at higher speeds. Anything else I might be missing?
