Is there a how-to for replacement of rear wheel bearings? If so, I can't find it! ::)
If not, can someone give me an indication as to where the best place is to get new bearings (ie. GM or pattern), how much I should be paying for them, and also whether this is a job best left to a garage or not?
TIA :y

At least you should have some scaffolding poles about :) ;)

I have done it at home, but it was not easy. I have a good tool kit including an hydraulic puller and that was not enough on its own to extract the bearing, I had to add a screw type pusher to help and then the bearing just came out with a lot of effort and swearing. If you do not have good facilities I suggest leaving it to a garage.

do yourself then you will know for next time ::)

Had mr serek help do mine and getting the hub and etc out was easy,the hard part was the bearing case,but a big hammer n chisel and some swear words i didnt now later and it was out. :)
New one went in easy with a tap and block o wood. :y
Remember estate and saloon are different.

A bead of weld around the outer race makes them practicaly fall out.

Simple, you weld a bead around the inside of the outer race (the bit that gets stuck).
As its inside the hub mount it cant expand, but as it cools it shrinks...

Now that's clever :y

some times take longer to take brake disc off, then replace bearing

I'd love to know why you all need to change the rear wheel bearings :-\ mine's done 245k and is still on the originals ::) yet reading through the help section, they seem to fail almost as often as wishbone bushes and HBVs ;D
-
Nah, they are actualy a rare failure its just when they do fail it can be a challenge unless experienced or you have certain kit.
I have done three in total (none on mine) as an indicator of how common they are and the first was a real learning curve, since that one my techniques and tools used have changed so its now not such a big job.

A bigger hammer? ::) ;) ;) ;)

lol, not sure I could have used a bigger hammer than the one I did on the first one ;D ;D ;D

I've done a few and most of those were re-replacements due using pattern bearings which just simply do not tighten enough. Use ONLY genuine from GM or FAG (which is, I believe, the genuine part) The two FAG's I have put in have been fine ever since.
For changing, hammers are of no use. Brake disc off, Drive shaft off (six allen-key bolts), nut off from inside the hub, inner hub comes out with help of two M12x1,5 threaded thread-bars and nuts (these bars go thru the wheel bolt threads) and then you can either weld a bead to outer ring as suggested or if it seems not too corroded you can figure out how to make a puller from these mentioned threaded bars.
Fitting a new one: put inner hub and bearing to freezer, heat the hub in car and put cold bearing in. Then let temp settle (you can carefully heat the bearing a bit) and put in the inner hub. Remember to tighten the inside nut to 320 Nm (or was it 300 Nm, bloody tight anyway).

Had mine replaced last year - 90,000 odd on the clock
Thought it was the Diff at first (eh, Serek!) ::)
Once changed - no more problems!
A bastard to get out. As some one's mentioned, need a bigger Hammer.
-
Thanks for all the advice guys! :y
So are we saying that I'm best using GM replacements, or is there a pattern part that is known to be as good?
-
Brothers were picked up yesterday on MoT, looks like it's time to get a new hammer

Joff, have a word with Sassenach - he's only in Trowbridge, and has all the kit and knowhow to do one in less than an hour !!! I know .. he did mine for me .. :)
-
Twigs use a quality branded or genuine bearing,
Then get bigger hammer and sharp chesil or a welder.

I like the sound of that! ;D

hi i was having similar noisy back end and checked rear bearings found right was slight play so took in hand and replaced with original gm skf bearing unit for 35 pounds i made up a hub puller and bearing puller to facilitate dismantiling and rebuild as i know from experience bearings dont like big hammers, so after rebuild took for a drive and was still making noise, so back on jack and found no play so pulled off drive shaft caliper and disc to sinp bearing freely on its own and guess what scrap also, had to settle for a FAG bearing this time as main dealer couldnt get another original in quick but i know its as good a bearing as SKF so rebuilt and car now runs sweet as a rolls, just while was there i sorted handbrake and put in some new pads pins and springs just bedding in brakes ready for MOT, cheers eric
BTW this is first time i have ever done a rear bearing on a omega ever and have had over 10
PPS there was no difference in saloon or estate wheel bearing
-
Saloon and estate bearings are very different, as are the rear arms they are pressed into ::)
Estate bearings are identical to Monaro ones fwiw :y
-
Do i sense a wheel bearing party in mr twiglets new shed happing.
As i got advisory on n/s/r bearing on mot lazt week.
just think all that oil and muck on that nice new floor. >:(

I'm sure Mr Twiglet has considered that, and coated his mirror smooth floor with Oil/Fuel/Chemical resistant anti marking epoxy paint :y
If he hasn't, you'd best hope it doesn't rain ;D

I checked the rear wheel bearing on vauxhall. Epc and they are the same part number and when ordered thru dealer I asked if different. And parts manager said there wasn't any difference because I had seen them listed different on interdebt anyway fitted and working great cheers eric

The rear bearings are different between estate and saloon,by about 3mm,so i wont be going to your dealer to get mine.
Could this be why we are seeing more failures,as saloon bearings have been fitted into estates? Discuss.
-
Nearly 250k on the original bearings, and still going strong 8)
I dread to think what you lot do to them ;D you might be on to summat though BG :-\
-
well using vauxhalls EPC disc and search the bearing part 90486468 you get the results listed for both saloon and estate cars even for the old superceeded part number was listed as same, and i dont doubt the parts manager in my dealer either since you dont know him you shouldnt be passing judgement, Eric

A computer is only as good as the person who programmed it. Same is true of data :y
I have a printed version of that which says different ::)
Still, not my car ;D
-
thought vauxhall would have got it right for their own epc, can you supply the correct part number for the bearing as i have another estate to repair, eric
-
No they are the same and thats according to all the factors,

Had a rummage and cannot find the sheet of paper :-\
Not wishing to be argumentative, but given the estate bearings are physically longer how can they possibly be the same or be interchangeable :-\
Jimbob bought his bearings from Allgermanparts a while back iirc, and there was a similar debate then.
Can we presume then that Vauxhall no longer supply one bearing, and if that is the case which one is no longer available?
-
i will check the measurements of the bearing as i have the old casings still here but looking at epc disc it olny lists the one for all variants of omega and when fitting my new bearings there was no spare room in the hub if anything the circlip was tight to get fully inserted back into the groove, as for life expectancy of my bearings before it could be me hauling half a ton of coal in the boot at times as well as the lpg kit and upgraded stereo, cheers eric
-
The last one i changed,on my other estate was ,to a saloon one,that we had. :-X
-
Had another look and still can't find the pages I have >:(
One thing I am sure of was that it listed all three bearing dimensions, and off the top of my head, the estate (and Monaro) bearing measurements are:
74x34x48?.
The saloon ones are:
74x34x45?.
They are, as has been suggested by others, DIFFERENT.
Whoever updated your copy of the EPC has probably bodged it. Seeing as the last Omega was built ten years ago, I am not surprised :-\

Reply 11 mentions width difference :y

-
I knew as did others there's a difference.
Now unless they now supply a spacer,theres a width difference,unless on the last run of omega's gm fitted tbe same arms and bearings to estate and saloon. We need old copy of epc to check.
-
the epc disc is original from vauxhall, eric
-
Number 8 as it happens :P
Your link to somewhere that acknowledges the difference ought to put the arguement to bed :y

Over to our illustrious leaders... :y
the epc disc is original from vauxhall, eric
And I put it to you that it is incomplete and inaccurate :-X
-
Just to add, the trailing arms are also different saloon to estate :y
-
So the case is estate rear arms and bearings are different, "me lud" 8)
Therefore me lud we the defense need the evidence to prove our case 100%, the defense calls the shopkeeper a mr robg of brisol,pictures please :)
-
yes i know the rear trailing arms are different as its totally different setup with shocks mounted under the floor i wasnt disputing that just that the bearings could be the same as per info i have, eric
-
Reply 47, and a linky aswell :y
-

Fixed that for you :y
-
Different aproach.
If you fit a 45mm long bearing in a 48mm long hole its going to move,if you put a 48mm bearing in a 48mm hole it wont move.. Me lud!

Fortunately Vauxhall realised this and provided a different bearing for each posibility ;D

i am from an engineering back ground and dont need told my job thanks nice to see this being kept social i would have had more than an eye brow raised if i had fitted the bearing with 3mm of room to spare, i dont know i vx made a mod to the arms thru the production run or not but its also possible, eric
-
Nope, you've copped the arse because your wrong ::)
-
and so it decends into name calling, eric
-
i checked back in a old trade club book from 07 which lists the saloon as 90510542 and the estate as 90486468 with only reference to it as another size KIT, REPAIR, REAR WHEEL BEARINGS, 39 X 74 X 39MM (NLS.- USE 90510542) must have been updates thru run eric

Don't have the saloon numbers as I have no interest in them :-\ but suspect the break point is early/mid '96 from the chassis numbers...

So clearly, there are two sizes, one saloon, and one estate ::) Searching by part number and/or reg probably only returns info relevant to that part :-\

You're welcome :y

i think i finally have got the correct info from firstline web page it lists saloon as 39ID 74OD 39 wide with the estate as 37ID 74OD 45Width so quite a difference, cheers guys, eric :y
-
closer :y

The calibra use's the same rear bearing as the omega estate
90486468. :)
