Hello All,
We have a 2000 XJ Sport 4.0 4x4 with 95k that we just bought from some friends. It has a few minor issues, but has been dealer maintained throughout its existence (not sure if that is a good thing... especially if its a Ford).
Anyway, the rear end (a Dana 35 w/ ABS) is making noise/chatter in two ways.
1. When at a stop, if one were to crank the wheel and start driving, the rear end sounds like the diff itself (possibly the quasi-posi unit) is whining & shuddering a little. Straighten the wheel and it quiets down (no diff action).
2. While accelerating through, say, 35~50 mph, there is a distinct vibration coming from the rear end. Off the gas and it goes away. Its definitely at the rear end as we've had it on a treadmill to get an earful.
Otherwise is drives normally (not turning or accelerating). Last time I checked it would be hard to drive and not do either of those!
A 2003 dealer Repair Order for this XJ stated that they assessed the pax side rear axle and bearing as bad (which they swapped), and that some small particles of metal were visible in the diff oil (which they refilled with new fluid).
The u-joints are tight, the xfer case is tight and the trans/xfer/engine mounts are pristine. The Jeep is not lifted, the D/S is straight and balanced (Oceanside Driveline took care of that) and D/S to input shaft alignment is within <1 deg (based on an angle gauge) of a friends 2001 XJ 4x4.
My experience (mainly with 12-bolt GM's) is that the input shaft bearing might be toast and the diff itself is likely bad as well. Since I'm scheduled to take a 1,700 mile trip in this XJ (while flat-towing the 95 I'm donating to my sister in law) I want to be certain that it will make it.
So, here are the question(s)...?
1. How hard is it to replace the input shaft bearing (the slip yoke bearing in the rear end)? If a shop press is needed, would a 4~12 ton Harbor Freight unit work? (i.e. would the press push straight down into the rear end or is a hand air-hammer needed due to the angle)
2. How hard is it to get the old input shaft/slip yoke bearing race out of the rear end housing? What tools would be needed?
3. Is there a good aftermarket diff that will fit right into the D-35 rear end?
Thanks for your time & for checking out this post!
PS: I looked for a specific post regarding this issue but thus far have not found one on a D35 ABS, slip-yoke bearing problem. Sorry if this is a repeat of another post...
