I just replaced the boots on the passenger side of my 100K mile 850T. It was a messy job and at one point I considered buying reman half shafts to make the job easier but when it comes to a $12 needed part vs. $250 for parts I didn't need, I opted for the boots.

The hard part was freeing the axle from the hub. The manual says to remove the axle nut (36mm socket) and tap the axle shaft free. It was more along the lines of break a 1/2" ratchet, break a 1/2" breaker bar, buy a 3/4" breaker bar, look for a 36mm 3/4" drive socket, use a 1 7/16 with a four foot cheater pipe push/pull like hell to get the thing loose, then whack the axle like hell to get the shaft loose.

Thanks to the Brick Board I was able to complete the job. Freeing that axle shaft was done by loosening the axle nut seven or eight turns, inserting an extension into the 36mm 1/2" drive socket and pounding on the end (it will get ruined) until it moves. The factory uses loctite when they build them and they torque the nut to 89 ft. lbs. plus 60 degrees. From there it was almost easy.

To rebuild the joint you have to spread a circlip and tap the joint free. My broke and I had to improvise the "tap" out procedure. Uggh.

In the end, I am glad I did it myself. Not only did I save some cash, I learned a lot and now I own a 3/4" breaker bar.

Good luck.
