I got a new front diff from Randy Rack and Pinion. I drained the diff after 300 miles to find alot of metal flakes. Did I mention that it pulls hard to the left in 4wd. It makes a clicking sound (like a broken CV) but it comes from the differential. It feels like I have a locker and a broken passenger axle shaft. Drive axles are in good shape. The 4wd takes awile to disengage and my right front tire barks when engaged, followed by a loud CLUNK when it disengages. Could this be a problem with the intermediate shaft or the ADD? I am stumped want a SAS, but have no job. Oh well looks like I'll be using 2wd more now Any tips or ideas about this damn diff. ??? :-[ ???
