Removing N/S Driveshaft.

Post by Club Tropicana »

I need to renew the passenger side driveshaft oil seal on my '93 N/A, because its just had a new box, but when I got it back i noticed a leak, and the mechanic who changed the box can't do it for the next fifty million years (what is it about mechanics? :roll: ) so I thought I may as well have a bash myself - i've done a fair amount of work on cars before. I bought a 'transmission oil seal set' from Toyota for 25 quid, but am only going to replace the seal that leaks. Can somone give me a step-by-step 'how to' if poss? Many thanks... :D

Jack car up securely and remove wheel ! :mrgreen:

Remove brake caliper - just the caliper, not the carrier - remove lower 12mm bolt, flip up over and slide off slider ( not bolt retained ! )

Leave it hanging on the trailling arm

Go buy yourself a 30mm deep set socket with a half inch drive and breaker bar.

Remove split pin and star shaped cover from main hub nut.

Jam in a extension bar between the brake caliper carrier and the rotating wheels studs / socket thats over the hub nut.

Crack torque off hub nut, remove.

Below the hub, you'll see 2x 17mm ( or 15mm - slips my mind ) securing the trailing arm etc to it... remove those 2 bolts and that will release the lower trailing arms to the hub.

Remove 2 x 19mm shocker nuts and bolts - leave shock in situ.

Free hub away from shocker, use breaker bar to push down on lower track control arm wishbone and lift hub from track control arm and push the driveshaft in over - so basically, your lifting the hub and lowering it towards the rear of the car as the rear track contorl arm is still connected.

Be very careful doing this as the components have a great mass behing them, so if you get your finger jammed, you will know about it.

Drain oil.

Pull driveshaft out !! Simple.

The driveshaft has a little snap ring ( figure of speech ) doesn't actually snap, but that stops the driveshaft moveing laterially when in motion.

Pull oilseal off, refit new - blunt head extension bar / socket, use hammer / rubber hammer to knock into position.. then reverse the above ! :D

The mechanic is repsonsible for his work - he may have nipped it refitting the driveshaft... I know had I changed a box out, new oil seals for a start - then you know, no further issues.

To refill - easiest is at the top of the box - big breather nut, remove that and fill 3.5 litres worth in, open up level bolt on the side of the box and fill oil in box till oil starts to pour out off the side.

Job done.

If its all been off recently, it'll all crack off easily too !! I'll give you 20 mins and half hour to refil the box !! :mrgreen:

hey, sometimes I'm usefull, sometimes not ! :mrgreen:

Oh ! Quick tip, you might try fitting a smaller socket inside the 30mm nut - supports it a bit more on the shaft when cracking it off... ensure you are square on otherwise your wasting your time trying to crack the torque off.

Dont' forget to tighten it up !! #-o

I did this, and apparently your suppose to locktight the bolts before you refit them, I locktighted one and thought sod the rest and just torqued them up as stated. After about 2 months all the bolts worked themselves out EXCEPT the one I locktighted in and after the last (un-locktighted) bolt fell out the whole shaft came loose and swung round the bolt and went through he side of the gearbox, ](*,)

I got a new box (1997 LSD) and modified my short shaft to fit and got the lot refitted properly

Yikes! I can soooooo do without that happening right now. So what are you saying - locktight all the hub/shock/everything bolts?
