Suzrub Posted February 20, 2006 Share Posted February 20, 2006 I have an 1989 push button 4WD and I really want to convert to D/R Do i need to change my gear ratios, will a LSD from an RX work in my car? Link to comment Share on other sites More sharing options...
Turbone Posted February 20, 2006 Share Posted February 20, 2006 Usually all 5spd 4wd trannies have 3.9 rear diffs. There is a sticker on the back of the diff that will tell what the ratio is. Unless its a turbo, then the ratio would be 3.7. Link to comment Share on other sites More sharing options...
subiemech85 Posted February 20, 2006 Share Posted February 20, 2006 it's a matter of matching numbers "normal" lsd is 3.7 if you have 3.9 trans, there are some 3.9 lsd available, or you could convert one yourself Link to comment Share on other sites More sharing options...
