Want to put some oil in the back diff, but its stuck really solid.

I know they are mounted on a fairly thin piece of metal and was unsure how much pressure I can apply without ripping it apart... whats the usual way round this?

Have you tied a bit of surreptitious heat?

Click to expand...

I really like to use the arc welder for those jobs, I put a nut over the stubborn bolt/plug/whatever and then lay a nice big bead down the middle. Sure, oxyacetylene works too, but the arc welder causes less collateral heating.

Put in a short 1/2in breaker bar hit once or twice with lump hammer into square hole then hit end of breaker bar good old fashioned shock should do the trick.-----BB

why not just take it fer a run, this warms the diff oil up, which in turn warms the casing up, then jump out grab a breaker bar, dive under the landy, and undo it quick while its still warm
