Hi all,

my 2004 td5 defender 90 is weaping a little bit of oil from both the front and rear diff pinions where the prop shafts enter.

The rear one isnt as bad as the front so im going to start with the front first.

I was wondering how you go about replacing them and whether you need any special tools to make sure everything goes back together properly.

Also whilst im in the process of this job is there any other simple things to check or look at? Just as a matter of interest

My defender has only done 64,000 miles

Thanks alot all
 
Have look at busters guides, be aware td5 has crush down spacer
 
I did mine on the back, no dramas.
Prop off, there is a 15mm (I think) bolt, that off retainer plate off, prise the old seal out tap a new one in.
Check your axle breather! Mine was blocked
 
What do you have to do when re tightening the retaining but? Just tighten it backup to exactly where it was before? For the correct pressure on the bearings?
 
Also whilst doing this job is it worth checking the pinion bearing? Someone told me it was easy to check whilst doing this at the same time?
 
I think I just tightened it, don't see how you could mark it accurately because the plate the bolt is sitting on comes off too.
How are you going to check the bearing?

just do it up tight, preload on bearings is achieved by a shim between the outer taper bearing and a step on pinion shaft, tightness off flange bolt/nut has no effect on bearing only ensuring it doesnt come loose
 
Ah I see, someone told me that the preload was achieved on the bearings by the tightness of the bolt onto a crush washer. If tightening it up just tight won't knackered axle up then that's what I'll do.

110 salisbury axle has a crushable spacer as do freelanders ,with which its not bolts torque that sets preload but the bolt is tightened until a specific rolling resistance is achieved,different spacers etc will require different torques to achieve that, solid shims are selectable in 2 thou increments ,the size of shim determines preload not bolt ,bloke told you wrong in both cases
