I can't find anything on the Useful threads page. Is it a simple job, how long and what tools are needed? Many thanks as I need to get it done before my imminent MOT as my abs light is on due to the snesor that's been lunched. I've had to buy a new hub .

[DarrylB]

Front or rear fella? Front will be slightly easier than the rear... I changed my front hub not too long ago and it's quite easy. Will PM you instructions when I get to work (in about an hour) as I'm on my phone at the mo

I just used the TIS guide when I removed them all last year. Rear are a bit harder as the access to the 3 bolts that hold the hub to the carrier is a little bit worse. Then there's obviously the driveshafts on the rear that you'll need a 30mm socket for, to undo the castle nut before a hefty smack from a copper faced hammer to disengage the driveshaft splines. Depending on the condition of your existing hubs, it can be hard work to get the 3 bolts moving as they get rusty. Likewise, I had real problems separating the hubs from the carriers as they'd nicely corroded together. But copious penetrating oil, combined with a hammer and a small pry bar finally budged them.

Dead easy chief. If your anywhere near macclesfield give me a shout and I'll help yuo.

[DarrylB]

Was gonna say exactly what Techie has said!

Here is the LINK to the TIS section where you'll find everything you'll need

EDIT: When I did mine, 24hrs prior to starting the job I sprayed all the bolts and joints with plenty of WD40 at every opportunity I got! It made life a hell of a lot easier and all my bolts came undone with out a hitch. Obviously if you have to use the car in those 24 hours try not to get any on the brakes!
I replaced the entire hub and hub carrier on mine (thread here)

You guys are good . @FLD you're a gent for your offer, unfortunately I'm not near you. Its the front one. Sounds like a couple of hours job to get it sorted.

don't worry if yours does not have a centre bolt , many turbos don't have them fitted from the factory. basically its the same as a brake disk change, plus the three hub bolts to remove http://www.speedster...Front Wheel.pdf

[oblomov]

I've changed one of my fronts this week before I took the car in for it's MOT on Wednesday. All I would say is that the 3 retaining bolts have shallow heads and they tend to be rather tight You may need a breaker bar to shift them so make sure you use a socket that grips on the flats of the nuts because if you round them off .......

[techieboy]

It's more that the bolts are slightly recessed. I ended up using a 17mm(?) ring spanner and whilst holding it on the nut, gave the other end a whack with a hefty club hammer to "crack" the bolt initially. Once you'd broken that seal they came out no problem.

Were is a good source of hubs themselves?

 

I vaguely remember someone mentioning they bought some that were slightly oversized and had problems fitting.

[oakmere]

Nev It has been said these are the correct fit: 1114 FRONT WHEEL HUB BEARING ASTRA mk4 G ZAFIRA mk1, 5 STUD SEE ITEM DESCRIPTION. 1114 being the important bit. I have not used them myself though. About £35.00 from e-bay.

[JG]

The bearing in the ebay ones are shit.

 

Elise parts .

[D3YMO]

AutoVaux are £70ea.

[Nev]

The bearing in the ebay ones are sh*t.

 

Elise parts .

 

How are you quantifying this, did someone buy some off eBay and have problems? Also, which ones on eBay please, I bet there are loads of different manufacturers, some might be fine and some bad.

 

What's the significance of the 1114 please Oakmere?

 

I really want to get some strong/robust ones, I think mine are getting shagged out fast by the grip

[oakmere]

I think the 1114 bit means they fit, as some out there the hub diameter is too large and require machining for the wheel to fit. I would be tempted to get the Autovaux ones but they are twice the price!

[mbes2]

I got all 4 from vauxcentre.co.uk ... all fitted fine

[TazN]

Fitted an ebay one and is going fine so far Nev. For half the price I expect it will last half the time or less but on the front they aren't exactly hard to swap if need be.

[oblomov]

If you're goin to soak the bolts in advance with a penetrating oil don't use WD40.  The WD stands for Water Dispersant which it is but it's not much use as a penetrator.  Best use a dedicated one or, one of the best and cheapest is plain ordinary diesel fuel.  Personally I've never bothered with the two I've changed (one front one rear).  The main thing you have to do when releasing the bolts is overcome the threadseal on them.  It's a fairly straightforward intuitive job, I did mine without referring to any guide.  The only problem I had was with the rear one re-seating correctly on the driveshaft but I posted a question about it on here and lots of people were helpful and the problem was resolved.

[james.a]

Are all four hubs the same?

[LY_Scott]

Yes.
