Asking for a friend. Seriously.
He bought a hot mess of a Jeep despite my warnings. 3"? lift with an 8.8 rear axle, no SYE, using a transfer case drop, and "new" rear driveshaft right before he bought it. He complained about a kind of slight knocking noise coming from the underside. After some futzing around we were finally able to replicate the sound at slow speeds. I immediately noted it was speed dependant and sounded like the right rpms to be a drive shaft. Shifting in to 4wd had no impact. I checked for play in both DSs but couldn't detect any. I did have him cycle between drive and reverse and noticed the rear driveshaft deflect a noticable amount. I think maybe his tranny mount is shot, but does this seem like a whole ton of exposed splines exposed at the back of the transfer case or an I crazy?
Sorry for the fuzzy pic. I didn't take it. It's hard to tell, but it almost seems to me like the slip yoke is just barely hanging on to the end of the splines and that's where the play is coming from. Am i way off base?
