Outer Limits 4x4 Board

Hey

I have a manual GQ diesel patrol and have a clunking everytime i take off and stuff and i thought it was a bush but isnt so i think its the transfer. I have a auto gearbox here out of a diesel patrol so will the transfer off that bolt up to my manual and if so is the gear ratio the same?? Thanks for your help

Have you checked you're Uni's?

yeah i have theres no movement in them at all. I thought it was going to be a bush somewhere but not that either. but when u grab the tailsharft u can feeling it in that so im down to transfer or gearbox. I have the transfer off a auto so thats why i wanna know if it will fit in so i can change it and see if that fixers it

Sounds to me like its the slack in your rear diff centre mate.
Take the driveshaft off at the diff end and turn the pinion sligtly and see if you can feel the slack in it there. Thats the common point.

If it is that, simply remove the centre and have the preload and backlash etc re done, and if you want to go nuts some new bearings. This will most likely be your problem.

As far as transfer goes. Im farely confident they are the same.

x2 for sure. To make it easier to check (as opposed to removing any parts), park the car on a flat surface, chock up the rear wheels front and back (so its chocked up tight), release handbrake, put car into Neutral, get under the car and at the diff end rotate the tailshaft.

If it is sloppy backlash, you will be able to rotate the tailshaft a bit before you feel the CW/P mesh and take up the slack. Rotate the tailshaft back and forth to get a better "feel" for the play.

Another possible answer could be axle spline/receiver wear - this was/is the case in my car. Showed all the symptoms of sloppy diff backlash, but on removal backlash was perfect. We tested axles in the centre and found that was where the play was.

NOTE: dont try and adjust the CW/P backlash yourself, get someone that knows what they're doing.

Ok thanks for that. hope it is that sounds easier to do that replace the transfer

i had a similan noise and i ended up finding play in the tailshaft spline, it was enough the clunk on takeoff and backing off, so check the tail shaft splines as well,
