Disco front bearing transfer box

[skip2]

Hi new here so hope you don't mind my post, ive a 200 tdi disco and the front bearing on the transfer box is very loose. The shaft wobbles about and whine like mad, oil leaks as well, done about 180K

Been to the garage but they are very busy although had a look, before I go back after chistmo is it right I need a new box. Can the bearing just be replaced ? Does the whole box need to come out.

Its not a bad disco some months MOT left but the repair cost outweighs the value is it worth doing?

you have probably have checked this but worth checking iff not, the flange nut is prone to coming undone, this will give you the same symptoms. drop the 4 prop bolts, and check the main flange nut. good luck. alan.....

if new bearing is needed peace of cake, new one from paddocks aboat £7 ish. the whole shaft comes out with bearing attached.

sorry should have said, box stays in just take prop off. might be worth  doing the rear one at same time mine went a couple of weeks after the front. little bit more involved as you have to take handbrake drum off. but still easy.(plus if that one fails you end up with no handbrake due to oil contamination on pads more expense   )

Interesting thread this.. my transfer box leaks slightly at the front, so i replaced the seal not long ago, still leaks, and whines like mad.... was gonna just throw another transfer box at it, but i might try changing the bearing, and oil and see what happens.... oh, and the seal again..!!

here is a post  did on plcuk

i have just changed the bearing on the front output flange on the transfere box. its quite a straight forward job but can take a little patiants Wink .... heres a step by step guide. ( look at pics in order )

1: remove the front prop shaft by undoing the 8 x 14mm nuts and dropping prop out the way

2: put the trasfere box in diff lock and put in gear. now undo the 30mm nut on the flange. this is quite easy with a large exstansion bar.

3: remove 2 washers underneath the nut. you should find first a steel washer and then a felt washer. remember the order that they came out in.

4: you will now be able to pull the flange assembly out

5: under the flange you will see am oil seal. prise this out with a screwdriver. be careful not to score the tranfere box.

6: you should now see a circlip on the outside of the bearing. remove this. you should now be able to pull the shaft and bearing out. you may need to use a screwdriver to pirse it out but with patiants it will come.

7: grease the newbearing up . replace the saft into the transfere bow and then push bearing in. make sure you tap it in gently.

8: now replace circlip and seal. then put on flange and replace propshaft.

this job is easy enough for most home mechanics to do. so if your box is leaking ep90 from the front seal then dont be too afraid to have a go.

It's a bl**dy big circlip. I ground down the end points of some old long nose pliers cos my circlip pliers wouldn't reach.

To remove shaft, just put the big nut back on and use a screwdriver to lever behind that to pull the shaft out.

Dead easy to do. Air tools help.....you can 'gun' the nut off.

Carefully clean up the housing where the oil seal presses in and use a bit of instant sealant on the outside of the oil seal and a bit of grease on the inside (where it presses over shaft).......obviously replace the oil seal with a new one :)

I replaced mine thinking that I have 'excessive play' in this bearing (there was no play in the prop UJs), but afterwards there was no difference. However, as the original poster has noted that his is making a noise then I reckon it's about due :)
