Hi i have a 98 chevy blazer lt. When ever i am coasting up a hill then accelerate i get this loud clink noise coming from the passangers side. The noise only happens while i am coasting then accelerate. i replaced the u joints so i know its not that. my truck is 4x4 but i keep it in 2 wheel drive. can having no fluid in my transfer case have anything to do with this? Please any advise would be greatly appreciated.
thanks

Any ideas of what the sound or problem is?

 

ok i took my truck in the shop today and the told me i needed a
front wheel alignment
torson bar adjustment
drivers side ball joints bad top and bottom ones
left axle boot ripped
right axle seal leaking.

i got the alignment done and torson bar adjusment done. so what else can be making this clinking noise when i accelerate when going up a hill?
