as it says on the tin!

trying to get into my LH rear hub to find out why it moves about10-15mm forwards and backwards(any ideas???)+ leaking oil which i guess is due to a fault seal and i cant get the halfshaft out.

Have removed all the bolts and it wont budge one bit. Does anyone have a good technique for shifting them

your help is much appreciated as alway

Hi mate,

I had similar problem with mine, went underneath for a look round one sun afternoon as you do!!
I found grease all round the inside of the tyre, jacked it up wiggled the wheel and I can't describe how much it moved, but I'm surprised the wheel stayed on!
It was a completely nakered wheel bearing, the hub had kind of welded itself to the stub shaft so i gave it a few taps to get the bugger off, think i warmed it up a little bit as well but that was last resorts!

I needed new bearings,stub shaft,hub. Also changed the diff oil in case any grease got in there.

Just had another thought you have taken both the wheel bearing nuts out haven't you?

you cant get to the wheel bearing nuts till you take off the half shaft as the end of it covers them (rear wheels not front) or am i being ignorant of something

No sorry mate, it must have been along day when i first read your post, I got it in my head that it was the hub you were struggling to get off.

I tapped the half shaft on each of the edges where the bolt holes are all the way round it (in a sort of outward direction, if that makes sense). Then slid out once I had seperated the two faces. Sounds like the face has just stuck itself to the hub.

well i've tried using a "hitting tool" to no avail aswell as putting the tip of a chisel between the 2 where there is a small lip and dispite walloping it, it still wont budge one bit

If you have removed all the bolts simply fit the wheel and gently try to drive off. This will make the shaft spin on the flange and break the seal, take it easy as you do not want to damage the faces of the shaft ect which is what you would do if you get in with the hammer and chisel.

cheers dave

just taking it for a short drive worked eventually, tho did take a little while

Did discover the reason that it was so hard to remove, and the reason why i was getting lots of hub movement/ noise...the whole internals of the hub had disintegrated and welded themselves to the stub axle and the whole assembly was being held on by the halfshaft itself

looks like lots of new parts for me then!

had this with my bearings, bloody inner races like the weld themselves on!

Yeah it's a right pain.

If you have to replace the stub axle, which i'm sure you prob will, make sure you give each bolt lot's of little gentle taps with a hammer. The first one I undid bloody sheared off, gave each one lot's of little taps after that and the rest were fine.

Yeah i do have to replace the stub axle, and the hub itself. I was ok with undoing the bolts normally , just needed a bit of leverage unlike my top rear shock mounts which did shear off!

One thing that got me going with the whole incident was that before i noticed that there was a problem, my brakes suddenly went and the low fluid light came on on the dash. So i stopped the car to have a leak to find out that brake fluid was pouring out the rear piston because the brake pad had totally gone! both retaining springs/pin and the other pad were there but one was gone. I cant see how this happened unless the force of the loose hub had smashedit into pieces as we were greenlaning at the time.

Anyway managed to fix it tempererily by switching the remaning pad over to stop the leak and had to top of the reservoir with power steering fluid as was the only thing we had spare to get me home. So now need to drain the whole braking system and re-fill with 100% DOT4 as it is v spongy atm, which i imagine is a result of the power steering/DOT4 mixture

ffs boy yer dint wanna be puuting any old fluid in yer brakes. it can cause the seals to swell up and fail big time. unless you can be sure the steering fluid wont do this yer gonna have to replace all yer seals and ensure you get every last trace of steering fluid out of the system.
if your brakes are still spongy after replacing and bleeding ah say yervu folked all yer seals

 

[discojamz]

yea i kind of gathered it wouldnt do much good ut didnt really have much choice stuck in the middle of no-where in wales with fcuk all brakes!

So i take it that it's gonna make me pay for this mistake
