True or false?

This makes sense to me but you guys give me your opinion. I changed my rear gear, got a new spool and 35 spline axles w/clip eliminator set up from Moser. I was told from DTS (a local drive train parts place) no need to fill it to the recommended spec because lube isn't needed to go down the axle tubes on count of the sealed bearing set up on the eliminators. I put in 2 quarts of the Amsoils Severe Gear 75W90. What do you think? Will I be okay this way

should be fine, i usually end up w around 2.5 in mine

Yeh, I think so, too. I run 2 qts. in my Fab 9. Swapped gear ratios recently and the ones I took out look great.
