Knock Knock....

no its not a joke unfortunately. i have a big thump from the rear when i take up drive and a not so big thump when i change gear. then when i bump up a kerb or making manouvres it knocks. also alot of vibrabtion at speed. UJs changed in rear prop not lot ago and they still feel good. front prop brand new. the only thing is there is alot of play in the rear diff, i can turn the flange alot more than the front. worn diff pinion and or bearings? answers on a postcard, or here will do. thank you

could be your rear shock absorbers or even a loose exhaust?! check em, you could be surprised

yeah checked them and A frame ball joint too but is is worse than that. kinda like a loose prop shaft UJ when it takes up slack not nice.
