Differential fluid change

[blulenium]

IHey does anyone have any advice on how to get the drain plug loose to drain the front and rear end differential fluid on a 2002 QX4. A buddy and I have both tried to turn that drain plug but are afraid of breaking the bolt or something. We've even used a breaker bar but those things are in there good. Before I break something or take it to the shop I wanted to see if anyone had any suggestions. Thanks!!

You need to heat it with a torch.

I had the same problem. You will round the bolt out before you get it out without using a torch.

Get a small handheld propane torch and heat up the bolt until it starts to glow (about 10 seconds or so if I remember correctly). It should come out real easy with a standard 1/2 inch drive rachet. Remeber not to touch it, it will be extremely hot! Just give it a few turns to break it loose and then let it sit for a few minutes to let it cool.

and make sure you open the fill plug first, just in case!

Hey thanks for the response, I'll try that route. Never even thought about heating the bolt up. Thanks again!!

Darn good advice Fueler... Make sure you can get new stuff in before taking the old stuff out!
