KANTANKRUS Posted June 6 Share Posted June 6 Warm to the touch, and after 5 seconds almost to warm to keep your hand on it? Does that sound normal? Diff, Chrysler 8.25 with 4.56 gears, running on 35 inch tires. Link to comment Share on other sites More sharing options...

ghetdjc320 Posted June 7 Share Posted June 7 Have you recently done a gear swap or changed bearings? Link to comment Share on other sites More sharing options...
gogmorgo Posted June 7 Share Posted June 7 Diffs run hotter than you’d expect. The gears are a sliding contact. Lower gears do more work and run hotter as a result. If the oil hasn’t been changed recently it might be prudent to do so. But if it’s not making noise and the pinion isn’t flopping around I wouldn’t be too concerned about it so long as you can touch it without feeling like you’ll leave fingerprints behind. Being barely able to hang onto something for five seconds is OSHA’s “safe to touch” test, standardized to 140°F. That’s not a concerning temperature for a diff at all. 200°F is kinda ballpark normal. You’d want to check the spec sheet on the oil you’re running but most should be fine up to 250°F. Link to comment Share on other sites More sharing options...
