RIGHT! I'm looking for an alternative to the driveshaft repair for the Q4 Brera/159 centre prop bearing failure issue, and i'm hoping the brains trust here can assist.
Yes, there are a number of threads here about 'my clunk', 'banging noise' etc - i've read what feels like all of them I’ve searched but I can’t seem to find anyone manufacturing replacement bearing parts for the 159 or Brera.
For those lucky enough to live in the UK, you can get it done by Driveshafts UK and it's a great solution at a realistic price from what i hear.
The problem for anyone outside the UK like me (i'm in Australia) is that we need to dismantle our car, have the part shipped to the UK, repaired, shipped back, all whilst our car is out of action (for i dunno how long)... which makes things rather difficult as you can appreciate.
Locally I have gone to two custom drive shaft shops (they do hot rods etc) but of course as is often the case when you want something done that isn't common, these tradespeople cant be arsed / don't want a headache so they never get back to you.
Mine doesn't need replacing just yet, but when it does, i want to be prepared.
I believe the "Alfa 159 Brera Q4" 4WD system is the Torsen Diff, which is also used in the VW Touareg, the Audi 4WDs, Porsche Cayenne and Renau’t Scenic/Kangoo’s. And if you check their forums (at least the Touareg’s) they all complain about the exact same thing as we do. Including the same BS tactic where their company, VAG, don't sell the replacement bearing, but only sell the entire bloody prop shaft.
Seems we are all surrounded by b@s#@$ds!
Alternative 1: Clamping Bearing:
So i see one enterprising company - Vertex Auto in the US of A - have manufactured a replacement clamping bearing that they say improves the OEM design, and fixes the problem in 20 minutes as you don't have to even remove the drive shaft.
It’s basically 2 half horseshoes, that you pop around the in-situ propshaft bearing. That bolts together, holds the bearing in place, and you are sorted.
Unfortunately, the design is specific to the Cayenne – so the replacement bearing they sell basically bolts into and becomes the housing.

Alternative 2: Re-packing the existing Alfa housing
Another alternative I found was on You Tube, where someone has made a replacement rubber packing - https://www.youtube.com/watch?v=8py-7Og9gOU
I can’t read german so I can’t understand this – but it looked interesting – and if your bearing is fine but the rubber perished, then this would be a pretty cheap and quick solution.
The beauty of this type of solution is I could order this part, and when mine wears, the mechanic can replace it instead of a driveshaft specialist.
Question 1: Has anyone found a manufacturer making replacement centre and rear bearings for the brera/159?
Has anyone heard of, or seen anything similar to that ‘clamping bearing’? Would this work with the Brera I wonder?
Has anyone seen anything like this re-packing rubber before? Where could you buy something like this?
Looking forward to your responses!
