This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Routine maintenance revealed a leak in the transfer case. This lead to discover a small hole in the case. This is caused by a part defect that breaks over time. Usually around 85,000 to 105,000 miles. The part is an "anti-rattle clip" that prevents the inner pump from of course rattling. When this part breaks, the pump then rubs a hole from the inside out. If this is not caught in time, the lubricating oil would run dry and this would lead to a drivetrain malfunction. I will be ordering a replacement transfer case. Yes old part will be available. Note: As of yet, the replacement part for this has no modifications to prevent this from happening again.
: the contact stated the transfer case punctured internally and the oil drained out when driving around 25mph. The contact heard a knocking noise and took the vehicle to an independent repair shop for inspection. The transfer case was faulty and the repair part was ordered.
I own a 2002 chev K2500hd. I have had several problems, but was unaware of this site to report these problems until now. First, the dryer switch on the ac went bad @ 34K. Second, @ 65K I had to replace the front left wheel hub assembly as talked about in one of the other complaints I read. Third, @ 95K my transfer case developed a leak and I lost all the fluid. A Chevrolet mechanic showed me a transfer case that had gone bad due to the same problem and had been used in 4WD w/out fluid in it. Another Chevrolet mechanic told me he had seen several of these and that "jb weld is your friend". so I patched the hole, and 10K later it developed a second leak in a similar location and also about this same time an electrical part (about $550) went out for my 4WD. Now at 130K it has developed a third leak! also starting @ approximately 50K, my rear differential has locked up on me several times and I have had to replace 4 cables on my tailgate. After being a Chevy man all my life I think I will look at Toyota.
Pump retaining pin on the transfer case failed, permitting the pump to wear a hole in the transfer case with sudden release of the engine oil. Chevrolet is not claiming knowledge.
