Vibration after instal HD rear springs
Hey All -
'90 YJ w/ '89 Cherokee 4.0L (no rear track bar).
I had an issue with a dragging noise in the right rear for about a year... sounded like brake drum rubbing backing plate but much louder... whenever I made a left-hand turn or starting acelerating from dead stop. I never could trace it down but figured it was something rubbing against something else as the rear end moved up toward the body.
Looked at the el cheapo (4-leaf) rear springs and they were exactly flat (no arch at all) when Jeep at rest. So I got some Old Man Emu 5-leaf springs and put those in with new bushings, new rear brackets, and axle U-bolts (supposed to be only a 1/2" lift). When I got all this in, the rear was sitting at least 6" taller and the rear springs had a good deal of arch (shock absorbers would bolt on but just barely at full extension).
Took it for a drive... noise gone (for the most part) and now I have a noticable vibration... I assume from a much steeper driveshaft (Trans to Diff) angle. Also the shaft yoke looks to about 1-1.5" more exposed than previously. The Jeep was not previously lifted and I thought a 1/2 inch wouldn't do much (which turned into 6"+). I'm sure others have had this issue. What does eveyone else do about this? Thanks
