Somthings just not right.

Since i re build the diff after it died the car seem to run the same but doesnt sound right at all. Firstly the diff is making noise not too much but more than before and the motor seems louder. Am i right to be concerned??

Hi Paul, have you put the diff plates back the right way, there are two sides to diff plates from when they get stamped out, look closely and you will see a rounded edge and a flat edge, you want the balls to run and the face with the flat edge, another trick worth doing is with some very light wet and dry to sand the diff plates to make sure there are no imperfections and the plates are smooth and flat, only use a small amount of diff grease, I only ever use Associated diff grease, I know I may be telling things you already know but even I forget to put things back right. hope you get it sorted

Ta for the info mate. I didnt realise the plates were sided ill have to strip it abd check. Also i could have used too much grease.

Hi,

Did you check the thrust-race.

Thats the two tiny plates and about six tiny ball bearings that sit in one half of the outdrive. These get dirty/gritty and sometimes the plates even crack.

Its also possible to crack a diff plate if you over tighten them; espesially if theres a flat on the inside ie D shaped rather than O.

have you checked the spur for grit? might have a tiny bit in which will make it sound noisy.
