Rear Aluminum Replacement Driveshaft
So I got around to playing with the rear diff. It has been noisy since I bought the Jeep. While reading through the service manual, my brother and I discovered that the noise could be due to the side load not being adjusted properly. I bought the appropriate tool and we opened it up and checked the pattern. Sure enough it was quite far out. After adjusting it, the pattern was very close to optimal. The gear noise is gone but the pinion bearing is trashed so it will have to come apart again.
We also discovered that the rear driveshaft is also in need of replacement. The rear u joint was clunky and the spline wobbled. I searched for a serviceable aftermarket aluminum replacement and could find only one thread on Jeepforum that dealt with it. Apparently a gent in eastern Canada had one created at Pat's driveline. The cost was $700 cad with shipping. That seemed decent so I called them here in Edmonton. I was quoted at least $1000. That is less palitable so I have been looking for an alternative. Anyone aware of one? Thanks.
