Sweaty Differential

[pathy1217]

Well i just moved out here to the Phoenix, AZ area and since ive been here some things have been happening to my Pathfinder. Not sure if its just a coincidence or the heat or what, but my front diff has started to have a slow drip and is gettin sweaty. Also where the inner CV axel end goes into the differential is getting sweaty too. Someone told me to put some teflon tape on the drain plug and it should stop it... Thought i would ask and see what you guys think. Thanks in advance.

Personally, I wouldn't get a roll of teflon tape anywhere near any of my drain plugs. I've never heard of using tape on a drain plug, and I worked at a shop for nearly 10 years. The plug should have a crush washer that provides the seal, replace that if it is leaking at the drain plug. It may be the case that moving to a dryer climate caused your seals to dry up a bit and start cracking, which would lead to the leaks. But, I'd just chalk it up to a coincidence. The only good way to stop a seal from leaking is to replace it.
