rear axle on c reg transit

[tom_moran]

hi all

im here to ask the experts! a friend has asked me to replace the rear axle on her c reg transit. now ive never worked on a transit before and before i go over and realise ive not got the right tools etc, i want to get it right first time basically.

ok first question is are the bolts to be used stretch bolts? as i know on some makes they are. im going to need to replace the diff oil but what oil and how much of it? and bleed the brakes up etc. anything else ill need to know? is there any tricks to doing these?

thanks in advance guys

bolts are not strech as far as i know i allways re-use them,the diff oil is ep90 3 ltrs should cover it

goodluck

[tom_moran]

nice one, thankyou very much. is there somewhere i can see pictures of what ill be working on? i know it seems odd but i wont get a chance to see the thing till it needs to be fixed.

i appriciate your help

Whats wrong with the old one and what type is it?

[tom_moran]

the diff died, not sure what you mean by type? the van or axle?

[AlanN]

If it was type 34 (square section, used on the MK3 too) with diff problems, then just change the diff, very easy. You could even find a better ratio, but remember the speedo pinion gear for the speedo.

im not sure what type it is tbh, ive asked her for pictures last night but she has no camera. i have the reg if that could help?

If there are 5 wheel studs it should have the easy to replace front loading diff, if it has 6 wheel studs an axle swap is easier

[tom_moran]

ive just arrived and its five stud so ill just swap the diff over. Next question is how do i do that??

[madmark]

pull both halfshafts and undo the prop,then undo all the nuts around the diff!
dont forget to have a bowl handy as oil will go everywere

[tom_moran]

thankyou! Thats helped enormously. Hopefully this will be the last question, can a jack the van up on the diff? As im struggling to find places strong enough to jack it up and put axle stands under it. I dont want to bend the chassis as thats game over

[madmark]

if you jack on the diff you will find the jack will get in your way,cant you jack on the axle????

[sidspop]

Jack under the diff then put stands each end of axle.

[tom_moran]

i cant thankyou enough guys, i really cant. I got the spare diff ready to go in, the old diff still in place but completely disconnected and draining over night. Only thing ive left to do tomorrow is to work out a way to get the fill plug out as it mashed to bits and like every other bolt ive undone today was so coated in 20 years of rubbish ive literally had to hack away to find them then spend 2 hours with a wire brush and cleaner before they were in a fit state to be undone!

Ill drop back tomorrow with the result as i know its nice to hear the end to things.

On another note, if anybody ever needs advice or help on a vauxhall you can find me at mk3oc.com with the same username as hear and ill be happy to help in anyway i can

[madmark]

glad to help mate, dont forget to do a nice gasket ,myself i would use sylicon sealer all the way round and that should stop it from leaking
