So, after months of battling vibes once I shift into 4th and hit 35-40 mph, and getting help here, I am thinking about changing out my rear pinion bearings. Would bad bearings cause vibes like the ones I have described? There is a slight squeal when im in 3rd or 4th gear and going up a hill.
So, my real question is, how tough of a job would this be to replace the pinion bearings (inner and outter)? Im by no stretch of the imagination a mechanic, but with instructions I have gotten a 4" lift on and did my SYE (with a little help from a friend). Is this just something I should bite the bullet on and take it to a Jeep mechanic in the area (Jeff Daniels Jeeps)? Input is always greatly appreciated. Thanks guys.
