I've got an '89 Wagoneer LTD (XJ). It's got a 3" Skyjacker lift, running 33's. Other mods are front sway bar disconnect, rear sway bar removed. Sorry it's long..but felt you should know the history.
Recently had issues with rear u-joint on rear driveline after a hard day's wheeling (vibes...obvious wear upon removal). I picked up a new u-joint and straps at NAPA. Things are OK after that.
Following weekend...more hard wheeling (getting ready for club's obstacle course)...broke rear drive shaft at rear u-joint. The "ears" on the shaft tore through and also scored the yoke.
Replaced driveshaft, u-joint, and differential yoke from my son's '88 (donor vehicle). Upon replacement...had serious vibe issues, but otherwise seemed to work OK.
Next week...event and competition. Prior to competion, took Jeep to shop...they were concerned with visible gaps between u-joint bearing cap straps and the bearing caps. Got new straps..still gaps (won't tighten down properly). Got "smaller" straps and I got the Jeep back for $140.
Ran the rally that weekend...first day (rock crawl, hill climb, etc. no problem). Second day, ran the obstacle course (hard) and finished 2nd..but with significant vibes..even at slow speeds. Noticed straps "stretched"...put new straps on, and finished the frame twister and loaded hill climb.
Driving home from the event with a 1st prize in the 35" and under class!! (whoo hoo)...horible vibes. Have confirmed they're from rear..and went to put in new u-joint tonight. Picked up new heavy duty u-joint from NAPA..and u-bolts instead of straps.
Now...here's the problem. The u-joints fit the drive shaft fine...but the u-bolt straps are too narrow for the yoke, but seem too wide for the bearing cap! WTF????
I know I'd need to drill out the yoke to handle the u-bolt straps (instead of straps with bolts), but the u-bolts I was given just won't work.
I was given Precision Heavy Duty U-Joints (#280), and they fit the driveshaft years just fine. I was also given Precision (NAPA) u-bolts (#329-10). They seem too wide for the bearing end caps, yet too narrow for the yoke holes.
Does somebody have better part numbers for u-bolts? How can the u-bolts be too wide for bearing end caps, yet too narrow for yoke holes?
Help!!!!!!
