\'96 Blazer LS 2 Door 4X4 - Help With Problem
First, let me tell you that what I know about 4X4 operation doesn't cover much more than what button to press, 2HI, 4HI, or 4LO.
I do know that I have to shift into Neutral and be just about at a standstill to engage 4LO. Anyway, I bought my first 4X4 for use in
snow when I lived in the NorthEast. Now I live in the South and have very little use for it. I want to give my '96 Blazer to my daughter,
who still lives up North, but, recently, I detected a weird problem with my 4X4 operation.
Since the vehicle was new, I had never had a problem with the 4X4. In March of '99 the quick lube place talked me into getting my
4 wheel drive serviced. Whatever that entailed, it took quite a long time. The other day, I engaged my 4X4 for the first time (due to
a moderate snowfall) and did I get some surprise! I'll try to describe the problem as best I can.
When I pres 4HI it switches into 4 wheel drive. However, it doesn't appear to shift smoothly, makes kind of whirring sound as I
accelerate, and, I think, it pulls to the right. My 4 wheel drive never operated like this before. When I press 2HI, the 4HI light goes
out but the truck does NOT disengage from 4 wheel drive (it's that obvious). After some period of time I hear a LOUD THUMP and
the 2WD re-engages. Normal operation returns.
Hoping it was something temporary (what else would such a novice hope for?) I tried it again days later on dry pavement (several
times) but the same thing happened.
That said, I called the dealer up North where I had purchased the vehicle new in 1996. Basically, he said there were three possible
causes and, in the worst case, all three would require repair. He estimated a cost of $1,100!!!!
Anyway, before I bring this thing to a local dealer, it would be helpful if I had some idea of what could be going on here. Someone
like me is ripe for a rip-off with something like this because I know next to nothing about it. Does anyone have an idea what the
problem might be and how can I minimize the risk of having the dealer charge me for a major repair while actually making a minor
Thanks for any help anyone can provide.
