anybody got any ideas about whats going on with my yj... it makes a clunking shuddering noise coming from the back of the vehicle .this mainly in first when letting the clutch out.. i suspect its the diff or prop misbehaving .. it only does this when hot and is worse on hot days.. oil is ep90 ls gl5 with mopar additive fitted but i dont think i have an L S unit fitted as when jacked up wheels act like open diff.. and it only looks like an ordinary diff internally... however there can be positive drive to both rear wheels as if the diff is locked out at times when applying the loud pedal it can be scary in the wet coming of roundabouts!!!! it also pushes the front wide in the wet first... understeer before big wadges of oversteer.. or is this normal
am considering changing diff oil for fully synthetic 75w90... of course the creaking may still be prevalent... is this about to go bang or should investigate further... also can any body help out with somewhere to get leaf springs for yj that don't cost a small fortune ? surely somwhere has standard springs in stock that dont cost the earth? been qouted over £400 is a bit much considering how much the cost stateside..
