True, But here is my dilemma with a quick history:
Gears installed 130k miles. Noticed noise on highway after install, speedo reading 100 mph (uncorrected, 74 mph actual). Shortly after couple hundred miles of babying it i notice some clunking in the driveline again at the higher speeds.
Pretty sure this clunking was there before the gears but I had only exceeded 100 mph once the week before the gear install (this is to relate to d/s speed).
I had a bad pinion bearing so by 131k miles the gear noise and clunking was so bad I took it back to the shop for all new bearings. It also seemes like it had a ton of backlash (would bang on every shift).
With all new bearings the gear noise was basically the same as before (not surprising with 1000 miles on them in a bad fashion), the banging while shifting was gone, but the clunking at speed was still present.
Now since I think it was there before and it is only when deccel at above 70 moh or so I think I have a bad u-joint and/or an out of balance d/s. If i can determine it is the d/s I can probably jsutify a new alum one before the prices go up much more than they already have. This is why if I can get another d/s in there and the symptoms of the clunking change or go away it is d/s related (turn the problem on and off).
If anyone has any other suggestions I am open to all thoughts.
I do also know that many guys have done gears then needed d/s work to make up for the higher d/s RPMs.
