I just put Poly bushings on both the front and rear of the Diff. I was surprised to see the rear mount stock rubber bushing worn almost completely through with so few miles!! I had to drop the diff anyway, so I went ahead and tightened up the backlash to .008-.009 while I was at it. Took it for a drive and there was no clunk! Lovin' it!! Just thought I'd share.
