cool I will look there first ty & ty for the welcome, what am I looking for broken teeth or something else

Yes spider gears inside the diff cup, broken pinion or ring gear.

Or could be the pin for the drive cup on either the differential or transmission. most likely the cause....

check the manual and exploded views to locate what I am referring to....

Welcome. Hope you get it sorted out.

thanks for the suggestions ,very helpful, will start checking today and let you know how I get on
can I ask another silly question, would the diff from an 1/8 acme warrior fit(have a broken one) asking as they are both 1/8 and I don't know
again thanks for the help so far

I highly doubt it would

ty for confirming what I thought but I was not sure and that's why I asked

hey guys , just a quick update , have discovered what the cause of the prob is, the rear diff had a spider gear which was in 2 parts lol. thanks to all who gave advice it was very helpful because I did not know where to start
