Guys:

For whatever reason, I decided to check rear diff temps after installing a welded 3rd. After 10 miles of driving, the diff is not scalding hot, but it is uncomfortable to touch for more than 10 seconds or so. I don't have an IR themometer to check temp. I'm wondering how hot is normal for a locked rear end. I never really checked the temp w/ the LSD carrier, so these temps may be normal. That said, would temps be expected to be warmer w/ a welded 3rd? Its worth mentioning that I don't think carrier is warped. It did not display any run out, backlash was in tolerance, and gear patterns looked ok.

Heck, I know a lot of guys w/ Nissans (xterra & titans, etc) that have had the paint peel off their rear axle becase of high temps.

Thanks,

Mark
