RUZN Posted October 30, 2009 Share Posted October 30, 2009 Did you set the diff up yourself? It sounds like you have to much Backlash from your pinion to crown gear are you sure you set correct backlash? As the gears wind up with torque they tend to seperate a few thousands of a inch. To me if its above 5mph that means the Pinion is contacting to closely or to far away. Metal shavings are generally not good even after 300miles.. Like micro bits ok as any loose material from casting will rub away. Do the bears have to much preload? Did you do a Tooth pattern check or just put it in. You should buy a dial indicator mount it and check backlash as well as tooth pattern wear.. It should be more towards Toe end of the teeth but directly in the middle. (Toe end means closer to center of crown gear, Heel mean closer to Back of Crown gear) The Differential is the center Casing Crown gear is the big gear Pinion gears are the smaller Straight cut teeth within the Differential casing Side gears are obviously on the side contacting your axles and the driveshaft is connected to the main Pinion Gear obviously Differential Housing is the outer housing that contains the Differential. Anyway I would check your tooth contact pattern make sure its in middle but slightly down towards the Toe (not to far) then adjust Backlash as needed with proper shims. Cause I think it sounds like your teeth as they load up are to high on the heel or to low on the toe or even perhaps the crown is to far right or left.. ya know? hehe lots of metals flakes usually means its to tight maybe not enough backlash or to loose to much backlash Quote Link to comment Share on other sites More sharing options...
matt_w Posted November 2, 2009 Author Share Posted November 2, 2009 I think you may be right, as I've pretty much exhausted everything else. When I did all my measurements when setting up the rear end, I found that I needed a 10mil shim to account for the smaller size of the posi unit. I bet I put it in on the wrong side Quote Link to comment Share on other sites More sharing options...
matt_w Posted January 6, 2010 Author Share Posted January 6, 2010 I moved the ring gear 10 mils closer to the pinion and there seems to be way less slop when I jiggle the ring gear around. I should have it driveable again this weekend, hopefully the clunk is gone! Quote Link to comment Share on other sites More sharing options...
F150toZ Posted June 25, 2010 Share Posted June 25, 2010 What is the end of the story? Were you able to get rid of the clunk? Quote Link to comment Share on other sites More sharing options...
