Diff bushing install
Hey guys what is your take on this method for installing diff bushings. Doing it this way Almost looks easy.
Energy suspension differential bushing install..with diff still IN vehicle.

Looks worth a shot. You still run a chance of not getting the bushings out cleanly, in which case you still might have to drop it all the way out to clean up the bores, but that looks like a simple solution to the job.
He partially got lucky if the air hammer was sufficient enough to get the bushing out. It's very risky using the air hammer around all of that soft aluminum, as it will tear up the inside of the circular housing if the air hammer slips. I've put some scrapes and scratches in the aluminum just with a hamer and chisel.
I've done at least 8 diff bushing installs and there is always alot of rust from the metal sleeve around the factory diff bushing. PB blaster and patience must be on your side.
I personally haven't even considered this method, because working under the car like this is very tiring, especially with hefty tools.

So I ordered the bushings from flyin miata and to my surprise there is no grease. I was told by a few of there techs the grease is not needed. Normally I would not questions FM but I see that 949racing gives you the grease and is 17 bucks cheaper. I gave 949racing a call and he told me you need the grease. If that wasn't enough the energy suspension instructions don't mention anything about the grease. So who's right does it even matter can I get away with using dishwasher soap/water or just any old grease for my installation. Thanks

I think all it took the last time I did one was a good solid effort with a blowtorch, and then a few minutes with an air hammer on each side. I think it took us an hour.

You can do it the easy way or the hard way,which one do you prefer?
Started last night so far I am not able to get out the bushing. So I either need air tools or I have to pull the diff. For me to pull the diff I have to remove the axels and the driveshaft correct ?
Just to clarify that... You blowtorched it while on the car? I'm sure that would make it a lot easier to get out.
Well The diff is out of the car now but I think I fucked something up. Can you guys tell me what you think of the damage and what needs to be done going forward. Thanks
