1 Ton Differential Oil Change Stubburn Bolts


Recommended Posts

Ok,

Can't believe that I couldn't get the filler bolt or the drain bolt out of my 1990 1 Ton Axle. (24mm socket)

I have been spraying with PB Penetrating Spray all day, hit bolt heads with a hammer, and tried cheater bars with no success.

Here is a cheap electric impact gun that I got from Autozone that worked like a charm.

3 seconds on each bolt , done deal.

I'm planning to flush and fill with Red Line 75W90 High Performance Synthetic

two thumbs up on impact tool

I have used a combination of PB Blaster for a couple of days followed by heat from a torch or heat gun and then I spray with a product that super cools the bolt. The combination of hot and cold seems to make removal easier. If you use a torch, don't over-heat the bolt to the point of burning things up.

The product that cools the bolt is called CRC Freeze-Off.
