Title: what gear oil to use to bring the whine down a little 80-90 or 75-140?
Post by: erickmarciano on May 07, 2009, 01:19:44

just adjusted the rotation force on the rear diff from 12 lbs to 16lbs and the diff now makes less noise . would the type of gear oil affect the noise? is so what to use to minimize the noise?
thanks

Before I tightened my diff drag, I had a definite whine betwen 45-60mph. After tightening it is barely perceptable and I can only hear it between 55-60mph with acceleration. I'm using Redline synthetic 75-90, don't know if it makes a difference.

thanks for all your past help ,the job was very easy with the right tools.my noise is only barely noticible at the same speed as you. hope I did not tighten it to much .
to all the others do you think synthetic would lower the noise even more?

thanks

Erik,

Can you define 'really easy' and 'the right tools'? I am about to attempt with another the replacement of my rear axle and will want to give it the once over beforehand.

Is the process one that is easily described?

James,

Did I read that right, you are about to take out the 3.46 axle and replace it with another??
