Changed passenger axle seal in Oct. 2003. Changed front pinion seal, front transfer case output seal, front u-joints Dec. 2003.
4WD Howls in AWD and 4Hi under load. Axle seal leaking again. TC output seal small leak again.I just had the front differential rebuilt. The guy that rebuilt it found the races of the bearings ( I am assuming side bearings ) to be pitted. He also found a small piece of metal about the 1/4 the size of a penny that he couldn't find out where it came from.
Well, I installed the differential today and the howling is as bad as ever.
I have seen a few others have had howling front ends in 4wd. I plan on taking it back to the guy who rebuilt it on Monday to see what he says.
Have I wasted $500 on a unnecessary rebuild? Does anyone know how to quit down these front axles?
My truck didn't make the noise the first 50,000 miles. My wife has a
2002 tahoe and it doesn't make the noise. There has to be something wrong.
