Exclamation rear diff plugs seized

My rear diff plugs are seized, I've tried WD-40 and a few drops of oil and it wont budge I've also tried putting the trolley jack under the ratchet to try and free it but it just ends up lifting the car off the ground.

Will it be ok to heat the diff up around the plugs?

Thanks in advance.

On the Forester forum they are saying it is ok to heat the diff up around the plugs. https://www.subaruforester.org/vbull...ck-help-81205/

Just want to know what the Impreza community think.

Re: rear diff plugs seized

Update, I ended up using a propane blow torch on the diff cover for less than 1 min then using a ratchet and the scissor jack (with the handle resting on the grove to stop it sliding about) and it came loose.

Not sure if the R160 rear diff holds less than 800ml of oil as I couldnt even get that much in even with the rear of the car jacked up so that the oil would run towards the front, looked around 700 then it started pooring out the filler hole.
