driveline whine, dealer cant fix

[thebear54]

Here's a thought Pete.....
Have them check the alignment of the drive shafts and U-joints. If the shafts are warped or U-joints are bad you will get whineing noise also.
If they are both true and straight then the transfer case is the culprit,even though they have changed it one doesn't mean that the replacement is any good.
Good luck......John

since it's rear wheel drive, my best guess it's your rear pignon bearing .

John, i'll pass that along thanx, i guess a duff transfer case even though its new is possible, they were quite sure that that was the cause before.

I dont think its the pinion bearings as they were replaced with the new final drive assembly.

Your VX is not lifted, is it?

Have they tried disconnecting the TOD to see if the noise goes away? How about running with one drive shaft or the other removed? Oh nevermind, this is an Isuzu dealer - they'll do it the long, expensive way....

LOL....TONE you are so right !!!!!

I just had the 60K(even though I only had 56K on the odo)transmission fluid/filter service,Tire rotation/Balance, front wheel bearings repacked and front brakes replaced at the local shop I deal with (NON-ISUZU garage) for less than $300.00.

If it had been an Isuzu dealer it would have been around $1,000.00, I'm betting.
It pays to shop around I guess.

Yal, no its not lifted, its completely stock, Tone...they did remove the drive shafts and it the noise did go away which is why they thought it was the transfer case and replaced it.

Its been in the shop for the last week while i was in San Francisco on vacation (what a cool place) so i feel very relaxed right now!! i'm just waiting to hear what happened from the shop manager .......will know more later!
