Thread: L322 Rear Tailshaft Removal and Refurbishment

I do currently get a "binding" sensation from the rear diff when turning full lock in dead ends...

[Edit - I should add that I changed the diff oil before filming today... It wasn't bad, it was golden, zero anything on the drain plug. Unfortunately I used an oil tray that was already a bit dirty, but I saw nothing shiny/metallic at all. It was mildly golden and I didn't clean the tray out with degreaser afterwards and the garage now smells of diff oil...]

I had a bit of an exhaust leak anyway so I dropped the exhaust to check it out and get at the propshaft. My old prop shaft CB was toast but the other joints looked and felt fine. The Hardy Spicer doesn't come with the rear CV studs fitted, but they knock out and in the new CV easily enough. It was a lot easier than I expected with the hardest part was refitting the exhaust by myself just because it's pretty heavy.

The shudder when accelerating has gone as has the exhaust leak, so all is good. Well it was for about 2km then the brake pad warning came on, so pads are next.

My shaft arrived today and the CVs on this new one feel very "firm", my old ones were much "looser" feeling and definitely bind. These ones, while "firm" or "tight" are smooth.

Might try and put it in tonight! Gonna be an easy job second time round.

Will also check / feel diff (jack one wheel off ground and spin diff without tailshaft in).


[Edit:

And done. In and feels good! Took it on a 30min drive and definitely sorted now. We end up on the freeway quite a bit and that's where it's definitely obvious (and also taking off from lights, etc) and it seems smooth now.

The old CV's definitely bind, even after having them repacked.

I removed the rear heat shield only, left full exhaust in. The heat shield is very easy to manipulate and re-manipulate back into the right shape.

As this is my second time doing this it was done in about an hour, including checking the diff (spinning wheel in the air). I did it over the dip in the driveway/gutter with the car on full height and some stands underneath just in case... Plenty of room!]
