Is there a common problem with rear axle failure on these beasts??? I have a 1998 QC 1500 with the chrysler 9.25 rear axle and it started a howl about a month ago. I can only turn the radio up so far! Took it to the tire shop and had the tiresbalanced and rotated (for free, Thank you Discount Tire!) and it still howls.
Jacked it up and ran it in the air (with jackstands, of course) and it howls. Removed wheels and brake drums and it howls. Removed the drive shaft, tried turning the pinion and it jerks. Obviously a bad pinion bearing. No leaks, though. Fluid is full on flat surface (checked it tonight).
I replaced the rear speed sensor about 2-3 months ago, that can't have caused this.
Anyone repaired these and successfully solved this issue? My fear is the ring and pinion are shot also (they're 3.5, according to the tags).
This truck only has 84k miles on it, due to mostly city driving. I am competent at rebuilding axle assemblies as I have an inch pound torque wrench,regular torque wrench, bearing press and pullers. I've built quite a few ford 8.8 and 9" carrier assemblies but not a Dodge.
Any gotcha's? Pointers? Source for good prices (I'm in Houston, Tx) Source for a good, moderate priced LSD unit to swap in while I'm doing this?
Thank you for your replies.
