Grease Points

There was a period where prop shaft UJs did not posses grease points so be prepared for a surprise!

I do know grease points were possibly fitted to UJs up to about 2007. On from then not sure but I can state unequivocally that my 2012 car does not have them. 

I believe that UJ grease points were reinstated at some point in the near past - 2015 > ??

The front UJ on my 2008 R400D has a grease nipple. The rear UJ has the threaded hole but the nipple is missing.  I only spotted this yesterday while under car cleaning the tunnel panels for my heat insulation kit. 

I assume there's supposed to be a nipple there?  If so, can anyone suggest what size?

Well, this is truly bizarre...

Before I proceeded to order a few 1/4" UNF long nipples, I thought I'd check by removing the front UJ nipple and trying it out on the rear.  Apart from the fact that it's very awkward to get in there (there's a chassis cross-member partly in the way), I could not get it to fit. The nipple was definitely 1/4" UNF (28-pitch thread).  So I tried an M6 x 1.0 screw, and it just slipped in.  I went to put the nipple back in the front UJ, but could not get the thread to start.  The reason was that the front UJ was also M6 x 1.0.  Clearly, someone (not me guv) had jammed in the wrong nipple in the first place.

I now have some M6 x 1.0 nipples on order.

Incidentally, there's a big label stuck on the propshaft saying something like "Ensure regular greasing of this unit with a lithium-based grease".

'Incidentally, there's a big label stuck on the propshaft saying something like "Ensure regular greasing of this unit with a lithium-based grease".'

And how many do practice the ritual of annual greasing ?  That is if grease nipples are present. 

From listening to some owners the answer is never !! Which must make the prop shaft UJs some of the most 'reliable' components in a Seven that is until the inevitable happens.

Any one had problems with the non grease nipple variety of UJ ?

The quality of the joints used on my standard 2006 propshaft were described by the guy who looks after my prop as cheap sh1t, he replaced both ad rebalanced, my first prop supplied new lasted 6 months and both joints were shot when the prop was removed.

I didn't pursue with CC as at best I'd get another prop with the same problem and I wanted the car on the road so had mine repaired while I waited.

Considering the close proximity to your thighs and the devastation a broken prop will cause to you and the car I would keep an eye on them, or consider a prop gaurd.
