Everyone should buy a can of this stuff. What an easy job it let me have. I started this morning about 8:00 on pulling everything out of the back end of the car. What I ran into was not the horror stories everyone has said about trailing arm removal. They took about 30 minutes for both to come out. The converter was the hardest thing by far. Now I just need to figure out how to clean the belly pan of the car. What a mess that rear end made when it started to leak.
I swear by that stuff...It's magic!!!!
PB Blaster saved me from having to replace an air strut on a P.O. S!@# 1989 Lincoln Continental. I let the strut valve soak overnight and it worked great.
I've heard P.B. Blaster is good but I have not found it anywhere in Canada yet. I will have to wait to get it next time i'm in the States the stuff the Ford dealers sell is very good. If It will loosen a Ford bolt it will certainly work on a GM.
