Stock Viscous Or Aftermarket Lsd

[prosman]

hey all

every since i got my 89 r32 gtst the diff has been a little clunky. it locks rather often in situations like sharp turns and u-turns which would lead me to believe its not the factory item (you can hear the inside wheel skipping). the problem isnt that it's locking up, during the corner there will be a horrible clunk once or twice from the diff which can be felt as well as heard. is this normal of an aftermarket lsd? if not can anyone suggest reasons/solutions? could it even be a rooted factory lsd? when ive had servicing ive asked them to take the back off the diff to check what type it was but they wouldnt touch it coz the hicas rack was in the way and they didnt want to screw with hicas.

all input greatly appreciated

cheers, andrew

if you thrashed the standard viscous unit it would simply lose effectiveness and become a single-spinner.

the clunking sound is the plates grabbing each other, most likely an aftermarket 2-way or something.

stock viscous units are very very lazy. that is, they dont really spin both wheels much.

furthermore, they don't clunk, unless if they're broken in pieces, i suppose they might.

generally, if it is quite bitey, and clunks, it's an aftermarket mechanical diff.

Some poeple like them, some don't. it depends on the use of your car.

e.g. if it's just an a-b car, i'd hate a mech diff.

for perfoamnce driving, i'd want one.

cheers for the responses guys! im happy with the mech diff and glad it wasnt another thing that needed fixing

my car makes the same noise when i turn a hard right and my diff is standard

shake the back of your car and see if the noise is there it may be something else
