Wheel bearing removal tool, help
Planning to replace the rear wheel bearings on my 996, hopefully off the car. Looking for anyone who can loan me the Sirtools B90-3J or equivalent and other accessories for this job.

The bearing can be changed on the car. I was able to change the wheel bearing on my 996 C2 many years ago using a the B90 kit and a tutorial from a boxster racing forum (they accomplished this trackside). It was surprisingly easy to do and was one of the few times Murphy didn't pay me a visit. I did but the new bearing in the freezer overnight before installing.

Chilling the bearing does not hurt but Heating the socket the bearing goes into has a far greater effect. A bearing will slide into a well warmed aluminum carrier without any force. The socket should also be cleaned and burnished of any nicks and burrs.
I have started to CAREFULLY open and inspect the amount of factory installed grease in every sealed bearing I use regardless of brand. I and others are finding many name brand and replacement brand with little to no grease.

The front bearings came out with difficulty (corrosion) and the “grease” had solidified to wax, could not identify manufacturer. Hopefully the NTNs will last.

I've tried freezing the bearing and under Kurt's direction heating the socket. There is no comparison--heating the socket to "gut-and-hot" and using a pole in the bearing to slide it in straight is very much better.

Kurt, I forgot to mention that I heated the hub with a HF heat gun. I was uncomfortable using a torch on the carrier.
I didn't even think to check the bearing to see how much grease was in there. That's good advice. Do you remove the factory grease and replace it with a different kind or is it ok to mix n match? If I ever have to do this again I will be sure to check the fill. Quote:

Quote:
I have both a torch and a HF heat gun - I can't imagine the heat gun getting the carrier hot enough for the bearing to just slide in, and sliding in is safer and easier than using the Sir Tools tool (which I also have). Did you get the carrier hot enough with the heat gun for the bearing to just slide in without any force?
