I have just put a R31 lsd diff into my ca18det ute and I took her for a test drive this morning and the axel tramps pretty bad... Have never had this happen before, but previously i only had a standard open wheeler ute diff in it... Now it tramps pretty bad and that is with some very worn tyres on the rear, would hate to see it when it has some decent rubber under it. So ill have to make up some anti tramp bars now, and the information so far has been great!
