Gearbox clunk??
« on: February 23, 2006, 20:07:45 »
Hi there I found a disco which i may be getting and he says that there is a clunk when taking up drive. Am I right in saying that this is the spline and if so is it easy to fit a new one and how much will it cost??

Cheers :o  :lol:

both my disco's have done this, i think its cos there is a slight ammount of play in the drive train, i.e. the prop will always have a minimal ammount of play no matter how good a mechanic you are.  All depends on how heavy and loud and the force of the clunk.

Its supposed to be the splined shaft between the gearbox and transfer box, theres a modified one available from somewhere that has a drilling to allow oil to the plines to lubricate them.  Mines been doing it for 3 years now.  Shortly changing to an auto and changing transfer box for a newer one so hopefully it will cure it.

If its a high milage truck there can be play built up all through the driveline from the hub flanges (front only on the disco) to the spiders, pinion lash, t-case and t-case input flange (which was an issue).
Mines been clunking since I've owned it, going on 5 years now, and so far still goes.  It all depends on how bad / hard it is.
I believe it's a pretty big job to change the input shaft.

If it's not leaking, it's out of oil

:D its not that big job to do go to the pto cover on the transvere box and you can check there but it could also be the rear ball joint :D this gives a simmilar clunking noise :roll:  have you tryed putting into neutrall for a few split seconds befor engaging gear i do on my auto and this seems to prevent the clunking to a degree gives the box a chance to catch-up/slow down for the other components that are still turning
