Help Axle arm bushing

[BExplorer]

I'm in the midle of changing my bushing in front and rear, I'm stoped at the axle arm bushing in the front. The instruction from Enrergie Suspension says to leave in the old outter sleeve and to burn out the rubber and retreive the inner sleeve. My probleme is the new bushing comes mounted with the inner and outter sleeve, but I'm not sure the assembly will fit in the outter sleeve of the old bushing that is frozen in the axle arm. Does anyone have ever change there axle arm bushing with Energie Suspension polyurethane. I cannot take the chance to burne the old one and burn the old one and be stranded at my father's place, I need to go back home by tommorow night. Thanks for any fast advise.

Bump!

Does somebody have any idea. I did the rest of the job, except the axle arm bushin and the springs one(du to lack of time). I would like to be able to have Poly all around, not a mix of Poly and Rubber.

Thanks
