Went to the mechanic to get an alignment recently and he noticed a crack in my front differential, the trucks 4wd engages both problem and the crack doesn’t seem to effect it is there anything I should be worried about?
A crack means a weak point. You strain ot to much and its liable to break. If you dont use 4wd and its not leaking though, could probably leave it for awhile. I would just fix it so its not constantly a worry in the back of your mind.
