Propshaft Overhaul

[Error404]

What measurement do you need Sal? I have a prop here I can measure

[sal_s2]

Its alright Alex, I've got a couple of props. I'm not sure whether the various suppliers measure from the same place. One of my props has the bmw version fitted but its split already, nowhere near up to the job

Cool, let me know how you get on as I need a new bearing to rebuild this prop I have

I'm still searching for the front half of an ABY prop. Anyone got one for sale?

Isn't someone on the forum supplying the OE prop bearing, at least a few years ago?
Was it GT500 or something?
I could be wrong though.

So Ive ordered the above, looks to be correct from the pics and measurement. I'll let you know once it turns up

I just want to mention a couple of things:

1 in the picture of the CSB you posted, the bearing does not look centered, it looks offset.
2 this seems to be an ebay only company, with no other internet or physical location. Just beware.
3 I would remove the seal from the bearing and take a look at the type and amount of grease in the bearing itself.

Just some thoughts.

Bearing arrived and I've compared it with an oe ur quattro one and the aftermarket BMW part fitted to my aby prop.
Qualitywise it feels much stronger than the bmw aftermarket item. The metal frame is of the same gauge steel and size as the genuine Ur Quattro one.
However the shape is different. The genuine Ur Quattro one doesn't have the wiggley bit but from memory I think the s2 version does? 20200622_205240.jpg

Something to ponder. I have taken apart B2 80Q, CQ and B4 sedan propshafts here in the states. The all had the "wiggley" bit in the center support bearing. I have also taken apart a range of propshafts that had replacement center support bearings, that ran a range of different styles.
Your UrQ propshaft may have already had a CSB replacement. That may be why they don't match.

That one cross-references to the BRG.A8 one further up the thread.

Have ordered one, will see what it is like when it arrives compared the the original.

I think i ordered this one https://www.driveshaftparts.co.uk/in...roduct_id=1751

was beefier than the bmw bearing, similar to the OE. Only thing i seem to remember was the kink on the support bar was the other side once fitted to the prop itself. I had a homemade alignment tool so i know it went on straight. No issues to date.

I'm pretty sure its original as its quite worn and the rest of the car was original also when I got it, having only had 2 previous owners to me. I'm going to fit it this week anyway, quality and fit-wise it seems bang on
