Last week I finally picked up a heavy duty slide hammer to tackle the rear bearings. Went smooth removing the bolt and hub, and now stuck at this point.

I have seen a few homemade rigs using a 6" threaded rod and 2-3/4 washers. It did not work trying to slide hammer the inner bearing housing out to outside of car. Will try that again after heating up but man this looks ridiculously annoying without the right tool. And to think I will have to do the other side now after seeing the condition of the bearings broken apart not looking great.

Harbor freight has a $99 set of bearing removal tools that will do the job.
Also good for installing the new bearing. Beating a new bearing in place will only mean you need to do another bearing job right away!!!

Thanks for the tip Chris, is this the kit? http://www.harborfreight.com/fwd-fro...ers-66829.html

Anything that can thread push a 2-3/4 bearing width out will work since smashing is probably the worst idea.

Yep, that's the one. I just used it at Watkins Glen last weekend for a track side bearing change!

The other fun part is getting the inner bearing off the hub - a two armed gear puller usually does the job.

Lol, believe it or not the inner race came off the hub by prying a small screwdriver at the base... Pling to the cement.

Picked up the tool tonight, took about 5 minutes to get the outer race cranked from the trailing arm. Following Clarks guide not having success getting the new bearing tapped in. Just put the bearings in the freezer so not sure if that is going to work or if the removal tool can be used in reverse.

If you dont start the bearing off perfectly straight it is much harder.

I did my rear bearings 2 years ago. I borrowed a tool from a friend of mine (owns a shop) and while I don't recall what it looked like (so I can't tell you if it was similar to what you have, though I do know it was a Snap-On unit), I do know that I used it "in reverse" to install the new bearing.

You should slowly, evenly heat the hub to 120C before removal/installation of the bearing. Look at the manual. The bearing will pull/push in without leaving a mark and if you freeze the bearing it will pop right in.

Use the removal tool in reverse!
Important to select the correct round disk that will push on the outside edge of the bearing otherwise you may damage the bearing.
You can spray on a little WD40 to help it slide in.
Cooling the bearing does not help much as soon as the bearing contacts the aluminum arm the heat transfers quickly enough that it does not make a difference. Cooling the bearing is good for front wheel bearings.

Yeah, that's how I have done bearings three times now...heat until bearing just pops out, while hot new bearing slides right back in. Also I use an air hammer/chisel to drive the inner race off, works like a charm.
