Thread: L322 Rear Tailshaft Removal and Refurbishment

Further, I believe this is the one I need for the front CV:

Driveshaft CV Joint Kit fits 2003-2018 BMW M3/M5/M6 108mm x 34 Spl 26112282725 | eBay

I'm pretty sure that's it...

Good news!

Took the shaft to a proper drive shaft shop...

The front CV isn't binding, it just has 0 plunge and is a "fixed" type CV, so seems like lining up the centre bearing so there's no load on it forwards/backwards is critical... It has been pulled down and checked and it looks great inside.

The bearing in the centre bearing is toast (float and loose), although the rubber looks perfect (lucky i had a new one ready to go)

The rear CV (100mm, i have no idea how many splines... but i assume 32 since the X5 has the same sized CV on the diff end of its setup) is "worn" but not "dead" - he's going to pull it down and see how bad, or if he can replace it...

So, assuming it's not a rare CV i might be back in business tomorrow (then i can share the part numbers)... Replacing the CV's yourself isn't hard once you have the parts, but he's knowledgeable and willing to help, so i'm using that while i can!

That's good news,

I've just bit the bullet and ordered a new complete driveshaft from Hardy Spicer for $800. Just for the uni and the CB I was looking at nearly $300 anyway and with the CVs an unknown I'll just change the whole thing.

Also it's my work car so I can't be off the road for weeks waiting on parts.

They sell them locally do they? 800 isn't too bad... I suspect it's going to cost 300 for mine to be sorted...

Edit - just checked The r catalogue....yup! They do sell one... interesting! What's the lead time on it?

Edit 2 - spoke with the company and they repacked both CVs, nothing worn on the rear one either, but repacked with grease and it's smooth now apparently, so maybe 17yr old grease had broken down a bit??? Hopefully I get to reinstall it tomorrow!

Yep they had 3 "LR-TVB00450" on the shelf in Melbourne. $820.71 with delivery to Hervey Bay from Melbourne and should be here near the end of the week.

I was pretty happy with the price. I expected the price to be well over a grand. When I called them to check the prices I had it in my mind if it was less than a grand I would grab one, over a grand I would order the parts from them.

Great! That's not bad at all!

So, all back together.

You can remove both heat shields without removing the exhaust...it just needs some bending of them and they bend back easily and fit back perfectly afterwards with some manipulation.

I've been out with the go pro trying to record what is going on as even though I had both CV's checked, cleaned and repacked, it's definitely still vibrating. Not as bad as before, but still not great. I assume a new CV means it's not transferring the energy as much.

I've now checked everything I can to try and work out what is vibrating.

The front half of the driveshaft doesn't appear to vibrate (as much as a go pro can tell you!)
The front propshaft (to front diff) seems smooth
The diff doesn't seem to vibrate at all
Neither rear driveshaft exhibits any vibrations
The rear half of the propshaft appears to vibrate and has a high pitched constant "tink, tink, tink, tink, tink" sound as it rotates when driving forward. When going backwards it's silent.

So, despite being repacked and checked, there must be enough wear in it to cause this. Unfortunately it seems like the rear CV is 99.5mm...according to Hardy's specs... I'm tempted to see if I can get a new joint and deal with it that way... Or I could follow step from above and throw money in the wind and order a whole shaft...hmmm

Here's an interesting view... I might make more of these... With a healthy propshaft next time!
