Rear hub bearing removal

[Kedishen]

Hi All

Will want to do my rear bearings sometime and I can't find much info about them on the forum.

Do i specially need to get a bearing puller to get them out or is there some other way that doesn't involve specialised tools?

The van has a Type L Ratio G axle, so 51a single wheel 6 stud heavy sailsbury less LSD.

Any top tips?

Thanks.

As i understand it, the half shafts should come off with a tap of the hammer and according to Minormatt, the bearings will come out with a hammer and drift... Is this that difficult to do? What size drift should I use?

Haynes drones on about getting them back in the right position. Any tips on this?


Also, are FAG bearings good? Or should I go first line/another make?

It will be a 5 stud axle on the 100.

No special tools needed - but the hub nut may need an unusual sized socket (I can't remember off hand).

Once the drum is off, you will need to break the sticktion seal between the halfshaft and hub before you withdraw it. A tap from a hammer may be good enough, but you may need to put a drift between the hub and halfshaft to knock it out.

Bearings can be replaced with a hammer and drift. The only alignment is making sure the new cups are facing the correct way.

Hope that helps?

Yep that helps. Thanks.

Its a 150 model. Just the vin plate and DVLA say 100 and ford etis and everything I read about transit on here tell me its a 150. Definately a 6 stud axle and running gear. Has 6 wheel nuts front and back + 15" wheels. Must be a reason it has wrong vin plate on but dunno why.

I shall have to change my sig!

I thought my Mk4 Hitop Custom was a 150 model - as according toford etis when i typed in reg and vin it tells me its a 150.

Anybody know the size of nut on 51a axle? (single wheel 6 stud)

[NeilsTransit]

According my diesel hard copy manual 1986-1999 (axle info seems the same as a petrol Transit) the nut size for the 51a salisbury axle is 2 ¼" so assuming it's a six sided nut then a 2 ¼" AF 6 point socket will do the job. Apparently the left hand side of the vehicle has a left handed thread on the rear wheel hub nut (Viewed from the rear of the vehicle)

See if you can de adjust the brakes first then remove the six nuts and remove the half shaft the bearings are held on by two locking nuts and a lock tabs bend the lock tab back so you can get the socket on remove first nut then remove tab washer and second nut and the bearing then if the drum and hub will not slide off you can use half shaft as a lever by bolting the half shaft back on the hub the wrong way round so you can use it as a lever move shaft op and down or Side to side and pull at the same time to get the unit off have used this method on Hgv s and psvs to get hubs off .
If you’re lucky you may get the drum off the hub before you take the hub off the van most of the time you need a press to separate them also it is possible you only have one nylock type nut holding the hub on I seem to remember a bearing kit from ford came with a single nut but we put it back with the old nuts and a new lock tab as we stocked them .
The first one we did we removed the hub nut with a blunt chisel we then made our own socket by bending a piece of inch flat bar round the outside of the nut to the correct size and size and welding it to a box socket

[MinorMatt]

On a single wheeler the drum has to come off before the halfshaft will come out.... so drum needs to be off to remove the hub.

Mk3vand earlier may be different

[cherniy_chack]

To remove the hub, remove the brake drum, remove the shaft, remove the ring from the hub hole, blocking the access to the 12-faceted nut by 65 mm, unscrew the nut (on the left-with the left-hand thread) and tap and remove the hub from the rear axle beam.
The bearing in the hub is fixed with a stop ring. After removing the ring, the bearing can be knocked out of the hub.
Before installing a new bearing, the hub should preferably be heated to about 100 ... 120 grams Celsius. The bearing will simply lie down in the hub without effort.

Only took nearly 3 yrs to answer Just make sure you mark the wheel-drum-hub otherwise theres a good chance you will end up with brake judder

Yep. Correct I had the same problem when last year changing a brake cylinder didn’t mark the drum and the shudder when braking was bad.
But luckily I had only a single drum off so it was back home removed the dual rear wheels on the side i was working on and turn the drum a single wheel studs worth forward and refit drum and wheels and take for a drive, worse so back start again it took to the 4th time before I found the original fitting and the shudder was stopped needless to say that problem will never happen again.......

Hey better late than never. But seeing as I did reply late, I didn't know about marking the drum for placement back as original till now so it's an ill wind that blows no good
