85 Gl Posted December 29, 2004 Share Posted December 29, 2004 my diff in me 85 gl 4wd d/r looks like it has a locked diff in the rear when i turn on the drive way i can hear it jumping on the innner wheel that i am turning i put one side on the jack and put it in 4wd and i could only turn the wheel a few inches then it would start driving the other side, so do these have locked diff Quote Link to comment Share on other sites More sharing options...
Qman Posted December 29, 2004 Share Posted December 29, 2004 Jack the entire rear end off the ground and then spin the wheel. If the opposite side spins the same direction it is a limited slip. If it spins the other way it is open. Quote Link to comment Share on other sites More sharing options...
sportsterbrat Posted December 29, 2004 Share Posted December 29, 2004 Does it say LSD on the tag? Quote Link to comment Share on other sites More sharing options...
85 Gl Posted December 29, 2004 Author Share Posted December 29, 2004 yep i no about the jack the entire rear off the ground and if the opposite wheel spins its lsd ill check the tag now Quote Link to comment Share on other sites More sharing options...
85 Gl Posted December 29, 2004 Author Share Posted December 29, 2004 yep i no about the jack the entire rear off the ground and if the opposite wheel spins its lsd ill check the tag now k i checked the tag didnt say lsd on the tag the gear ratio was 3.9 so im guessing it is a lsd, i just dont think it is tho because ive never seen a lsd work like that my bro has a ford with lsd in the rear and it doesnt do that the diff in the suby is working more like a diff lock Quote Link to comment Share on other sites More sharing options...
Skip Posted December 29, 2004 Share Posted December 29, 2004 you should go back and read Qman's post more closely. You have an open rear diff but a locked center diff this is what is causing the jumping, NOT the rear diff. You brothers truck no doubt has an open center differential.
