Oh man im so fkin excited right now. Last time i had to remove the auto pilot bushing it took me like 2 hours with a dye grinder then a dremel. I just finished the job in less that 5 min with no hassles at all.

Well i had heard on this forum that you can do it by packing the bushing/crank shaft with grease, then getting a like sized piece of metal and using that plus the grease as a hydraulic piston. The pressure created by the grease and the piston would force the bearing out. All sounds great in theory, so i decided to give it a try. I started looking around for something thats the same size as the bushing, i couldnt find anything that would work. So i decided to use our ancient lathe to make a piece that would fit.



After i made the piece, i packed the crank with grease. You want to use something small and thin to try to get as much of the air out as possible. I took a 5 pound sledge to it, and about 5 swings later the bushing popped out. Was grinning from ear to ear, good stuff.



On a sidenote, if anyone wants to borrow this tool i made id be happy to rent it out to you, just shoot me an email at [email protected].

I agree, easy way to do it. Try a socket that fits, stuffing it with wadded up electrical tape.

Autozone has a tool called a "Blind Hole Puller" part number 27128. It costs $140. You can "rent" it buy buying it, using it, and then returning it for a full refund. It's not even a scam on your part for doing it. Thats how they rent their tools apparently. I just did this last week and it took about 5-6 hits on the slide hammer (included) to pop the bearing out. Plus I didn't have to clean up the grease afterwards.

The hydraulic method is still a neat trick though.

i tried that tool from autozone on an auto pilot bushing once. i broke the damn tool. good thing the guy at autozone was cool and said "**** happens" and gave me my money back. after about 30 mins with a dremel i finally had it out. i still have it hung up on the wall in my garage

Hello sir. My name is David. My mechanic has been having problems removing this automatic pilot bushing on my 04 350z. I ordered a motor not knowing it was automatic. I just read your post and am dying to get this done. My car has been with the mechanic for 2 months. He works 12 hours a day and doesn't have much time to work on it. I've spent $4500 on parts motor and labor. Please help a brother out
