Rear bearing and hub fitting - just a couple of pointers.

Just posting this as it may help others to avoid a couple of pitfalls that I haven't seen mentioned on here before.

Car is a 2006 GT JTD. After extensive research on here I prepared by buying a 4in hub-puller (7 from eBay), a 32mm socket for the hub nut (4.95) and an angle grinder and disks in case the old hub "race" was jammed and I needed to cut into it (25 off eBay. silver line).

Okay, first problem is that the hub nut is really tight. I strongly recommended you loosen this with the wheel still firmly on the ground. This means jacking the car up, remove wheel, prise off hub nut cover with small screwdriver and push out the alfa cap from the centre of the wheel. Put wheel back on and drop the car.

With an 18in breaker bar I couldn't budge it but luckily I had a steel tube in the garage to use as an extension and this allowed me to loosen the nut.

With the car back up on trolley jack it was off with the wheel, off with the brake calliper and then off with the disk securing bolt thingy. I DID NOT have to touch the caliper carrier - it was possible to get the disk out with a bit of wiggling.

Then it was off with the hub nut and then I was ready to attach the puller. I didn't need it! The old bearing and hub just slipped off easily by hand - it didn't even leave the old race behind! Happy days!

I'd bought a new SFK hub fom AltAutos (thanks Steven) which had a plastic ring in the centre to hold the bearings in place. I couldn't figure out how to get it out. It was in tight. Eventually I decided to push the new part onto the axle thinking that would push it out. It did, but one of the bearings came with it!

Spent next 2 hours trying to push it back to no avail. Tried G clamps, everything. Nothing worked. It was the front race which had popped out. With much messing I ended up with the rear race out too. And then the front one just slipped back easily. The rear now wouldn't go back in.

Anyway, I ended putting the whole thing back onto the car and decided to press the race in by just doing the hub nut as tight as I could. It worked. There was quite a loud thunk as the bearing went back in and I just hoped I hadn't knackered it

The hub was now spinning freely and I finished tightening it up with the extension bar.

Everything back on and the wheel spins nice and quiet now. Test drive was whine free.

So moral is - watch out for that plastic retainer. It's a b@stard!

Just did mine .. the race stayed on as it did last time so angle grinder to thin it down then crack it with cold chisel ...

The plastic part is simply there to keep the inner races in place and shouldn't be too hard to remove.

You'd find it very hard to remove the caliper mount on the rear without major work. You can't get to the lower bolt with the tranverse arm in place. Alfa for ince realised this and made it so the disc comes out with it in place.

New one really was tight but eventually got it on .... and yes the nuts are meant to be tight ... they are supposed to be over 300Nm on a torque wrench ...

I couldn't work out which one it was this morning .. it started to really rumble last week so has been off the road. Tried the usual tricks of spinning the wheel and feeling spring but just couldn't trace it. Even tried fronts even though I was convinced it was a rear.

Drove around local roads and eventually got SHMBO to drive and I sat in back an listened .. eventually decide N/S/R ... that run-around was a max of about 6 miles ...

... and this was the tyre I took off ...

That is missing rubber ... not extra cr@p stuck on btw!!!

It appears to be the nearside rear that goes first on these cars! Which make replacement did you fit gazza, and did it have a plastic retainer? If so, did you manage to just push it out using your fingers?
