Broken rear drive shaft knuckle
Yesterday I noticed a slight vibration when I would come off the acceleration, but then it would go away quickly. Today it started to squeezing a little on deceleration, especially when downshifting. So I was just driving home and the knuckle on the rear drive shaft broke, and banged around the underside. Then it came off. Here are a few pics. What the **** could this be?
Well not trying to be an *** here, but what I see is a failed U-joint that broke and the actual driveshaft knuckle as you call it broke from slapping the ground/undercarriage. The whining that you heard was probably the bearings seizing up in the U-joint cap from lack of maintenance. Like I said not trying to be an *** but a little grease here an there go's miles further than no grease and a dry U-joint. Honestly i am a little anal retentive but I hit every grease fitting no less than once a month on all my vehicles and always grease ever fitting after going offroad after a good undercarriage wash.
Yeah I did just take it off to tighten the pinion nut. And did not think to grease it. Plus I just washed the **** out of the undercarriage after muddin. So just slap a new knuckle and grease her up huh?
honestly that driveshaft looks pretty beat up id look for a good used one on CL or local pull a part. Also from the pictures of the rear housing on your transfer case looks as if the seal is fubar'd if not the housing it's self really cant tell from the pics.
Alright well I'll be out of town the next few days. Bogleparsons - I'll take a look at see what mine measures out to when I get back. I'm hoping its just the knuckle. Should I take that transfer case cover off and inspect that shaft, and replace that seal? I'm hoping the problem originated from the knuckle and not the transfer case. Is there any way to tell?
