Well, I was using Diaqueen on my transfer case and rear diff, I road race and also drive daily my car to visit customers, so basically I drive a lot my car.

I decided to change (and try again) Redline Shockproof in my transfer case & rear differential (shockproof light 75-140) this time. But happened the same problem I had with the Shockproof Heavy, during acceleration from a stop, turning left or right my car starts to vibrate like if I had a bent axle or something messed up in my drivetrain. Last time I changed back to the Diaqueen fluid and the vibration was completely gone, I decided to use Synthetic Oil on my Transfer and rear diff, just to have better oil in there, but the vibration is really driving me nuts.

Any idea as to why this is happening?

Any advice is well received, I recently got a bottle of GL5 Mobil 1 75w90 Limited Slip Oil, will this one work or is there any better option?

Thanks for your time,

 

Bump!
