My 320i has ABS, as far as I can tell this isnt standard on all 320i's and I need a new hub, so I quikcly need to know is there any difference between an ABS car hub and a non-ABS cars hub?

yes there is the one for abs has a toothed ring around it for the sensor and the non abs one dosent

So would the ABS one for my 320i for instance be found on a 325i?

Really need a new rear hub ASAP

Can anyone offer help? Just need to know if a 325i hub with abs will work on my 320i without changing brakes etc

325i abs hub should be fine

good luck getting the fecker off!

Yep, same hub.

Is it a bit of a feck of a job?

Any hints and tips?

Yeah, how the hell do you get it off!!??

I'm hammering the hell out of it from behind trying to drive it out of the bearing, but I'm getting nowhere fast!!

Hit it harder! I hope you have a new bearing at the ready.

The sensor ring is on the drive shaft CV joint, only difference is a drilling on the arm for the sensor

so the hubs, ABS or not are identical?

AFAIK, this is for disc brakes I take it?

careful, i believe there are two different sizes of disc hubs, i just dont know why yet.

Yeah, its got disks all round, rear has disks with the drum handbrake part.

Oh ffs, so the little cash ive got left may be spent on a hub that wont work why cant life be simple.

Those are both from disc brakes?

Ive seen different sized bearings listed but would of thought it was disc/drum differences

Ive seen different bearings listed for ABS/Non-ABS cars?

well, thats how eurocarparts list em!

Hell, at this rate I may just take my hub off and have a go at tapping it from the otherside to see if I can get the facking thread sorted.

well dont be too disheartened, my theory has been roundly dismissed as the ravings of a lunatic so far.

i cant read the part numbers properly so i cant even prove it is off an e30 but i dont think any thing else uses e30 trailing arms so i dont see how it cant be. i also dont know if the difference is between abs/non abs, pre/post facelift or 320/325.

i reckon the easy way to spot the difference is by checking the size of the driveshafts on the donor car with the ones on your car. if they are the same size then you probably will be ok. my odd set are a few mil different in diameter.

I think the ABS hubs are bigger, but my 320 touring has the bigger hubs and No ABS, the wheel bearings are also different sizes...


With my car having no ABS I bought a non-ABS bearing.


As for getting the old bearing out, once the circlip is out then just smack it, it's already buggered once the drive flange is out so just go for it

You will need some threaded bar, nuts, washers and a big socket to wind the flange back in so it doesn't push the back/inner race out of the new bearing.

Here’s the best tip I can give you though, leave the new bearing in the freezer over night before you fit it and you could also warm the arm a bit with a blow-torch, makes it much easier to fit

yep, both off disc arms that i stripped myself.

Im just getting a bit wound up, want to drive the damn car, going to get it up on the drive and get my hub out, and re-tap it!

no poitn spending money on a hub that may or may not fit! plus ive only got £18 to my name at the moment (going to have to scrounge money to get new bearings!)

just measure the hub before you buy it, abs should be 52mm outer diameter on the machined part, non abs is 48 iirc.

I wonder wtf thats all about then, abs/none abs terms are also used for listing brake hoses when all it really means is drum/disc brakes

pass mate, confused the hell out of me when i discovered i had a non matching set of arms, hubs and driveshafts.

Need some tips, been trying to get the hubnut off with no such luck, ive got it so the hub doesnt spin but i cant break it with my airgun or the largest breaker bar ive got, any tips on how to get the fecker off?

i take it you need to tap a wheel bolt hole, cant you do it with the hub on the car?

Is it really secured so the hub isn't moving or is keeping the hub still half the problem?

Have you tried some heat on it perhaps? Or maybe you can find something silly long to go over the breaker bar?

Maybe you've done that lot but worth a mention.

if you do need to take the hub off, have you taken the locking ring off the nut, if so just get your breaker bar on it with a jack handle or similar to give you some leverage

More leverage easier it becomes...

Got the nut off just now (havent had the time or light to do it up until now)

Cant quite get teh hub out, am I not doing somethign thats vital to getting it out? i can near enough push the driveshaft's output shaft out the otherside (well not all the way) would it make removing the hub easier if i were to remove the driveshaft completely?

Yes you need to undo the 6 bolts holding the driveshaft to the diff's output flange and remove the shaft compleetly, be careful not to let the shaft hang on the outer CV joint though, the rubber boot will probably be a bit fragile and mine split

Ahhhh right, will do that in a minute.

took me 3 days to drive my old bearings out of my arms, with them off the car, in the end i got a thick threaded bar with some sod off washers. and some blocks of iron, set the bars up, wound the torque up until i could feel the thread on the bar about to turn into chocolate and smacked it with a sledge hammer to release it. they can be fucing stiff without a bearing press. i manage to twist i 1inchx1inch steel bar with the toque i put on the sod off breaker bar i was using to wind up the sod off bit of threaded bar.

I used a bad mood mixed with a 10Lb lump hammer ''Get OUT ya bastid''

Swearing at it while beating it with a big hammer probably didn't help, but it felt good
