Rear Propshaft centre bearing: How much movement?

Having felt vibration that comes in at about 55mph, I’ve found that there is significant movement in the rubber centre mount on the rear prop.
Does anyone know how much is acceptable here, as I’m thinking that any is not right.
It doesn’t take much effort to shake mine and see the prop move. The rubber is not cracked or broken up- but is notably “soft”.
Thanks in advance.

No movement..

Thanks for the quick reply.
Mine clearly has an issue then.
New GKN just ordered from JGS 4x4, and they've marked it as despatched..
Marvellous!

Thanks again.

You will need some E torx spanners for the rear prop flange bolts and they are bloody tight!

Try them but I think you will find they will be to fat

I just got the cheapest E torx spanners money could buy from ebay and they stood up to a pounding from a hammer so passed my test!

When you have the old prop off, give the rear u/j a good wiggle and I bet its all notchy.

Bardley - how much did it cost?
Reckon you’ll be able to use all the fixings again or is there a fixing kit to buy as well??

Please report back on how you get on as I’ve got to do exactly the same thing Smile

Thanks for the spanner and manual work thro'.

I ordered the prop from JGS as I use them for parts for my D2. Fitting kit incl. bolts is about £40.
The prop is a GKN one. It'll be with me on Monday.

2011 D4 130k propshaft centre/rear UJ very notchy...

Changed the rear prop shaft this afternoon, having had vibrations at about 55~65mph.
The bolts were worryingly loose at the front, and didn’t have the lock tabs bent over..🤨🔩.
The rear were tight, but again not anywhere near the torque setting or an issue to undo as reported on here.

The one thing that is worth mentioning is the centre bush/rubber mount. This was not as worn as I’d thought when I examined it on the car. There was up/down movement in the rubber. The OE GKN replacement had a fair amount of movement too.
The main defect and worn areas on the old unit were the UJ’s. The rear one (Diff end) was very notch and could best be described as having three positions. It would click thro’ as it was moved. This was evident in both planes of its movement.
The centre unit was also clearly stiff and nowhere near the new one in feel as it was also moved.
The front had a notchy arc, tho’ not like the rear.

The job took about 35mins. On a ramp.

Good Vibes..

It seems that they’re gone. Thanks for that Manual upload a few posts back- very good of you.

Next job is chassis wire brush, black chassis paint on the rusty welds, Waxoyl Clear..
It’ll need front discs and Pads at the end of the summer, then EPB shoes.

I’d really like my timed climate turning on.

thanks for the report - how high ramps did you use? reckon it's doable by blocking up each wheel on the drive?

did you manage ok with a half inch socket set?

Tools..

It’s do-able with suspension lifted (.. and secured with stands!!), though any extra height you can get would be helpful.

The heat shield unbolted easily.
It’s actually not difficult at all if you’re competent. You’ll need a Torx spanner / Socket set, not conventional hex head remember. Something like this:

https://rover.ebay.com/rover/0/0/0?mpre=ht...2370921862

and this:

https://www.ebay.co.uk/itm/US-PRO-9pc-1-2-...2749.l2649


I used the E11 long spanner for the front, and a socket for the rear with a 1/2” drive bar initially, then ratchet.

Rear needed an E12 or E14 socket, and not too much effort as I said. If yours are tight, then the higher you have the car will make getting an extension bar on easier.

Centre bearing uses hex head bolts, and I Copper- Slipped mine when I put them back.

Mine was on a ramp..I just rolled the car forward to move the prop and get to the initially inaccessible bolts.

Be Safe when you do it... I was in a Pit. If you roll it fwd, you’ll need to get the body propped again before you go underneath.
