I am working on a Fiero that has the axle support bearings, well at least one. The girl whos Fiero it is said, she woke up yesterday and a huge oil slick in her driveway.
I haven't had a chance to work on it yet, but I know it has the bearing on the side that is leaking, one day fine, next day dumping fluid.
I did a forum search and all I find is they leak and to use alot of sealent installing them, It was fine for years then one day oil slick. I would post the pic she sent, but it is like watching someone bleed out.

Enough back story, is there a trick/way to remove it? I figured I would ask as I haven't delt with one yet, before I jump into it. Axle seals yes, but not the support bearings

Thanks in advance

Going off of personal experience, good luck........
I installed a set of these bearings back in 2001 and put up with leakage issues until a couple of years ago. The only way I could get the bearings out (1988 Getrag 5 speed) was to split the transaxle case and press them out from the inside! I had the transaxle out for a clutch change, so it was one of those "while I'm here" decisions. I still had to use sealer on the replacement axle seals since the bearings had marred the hole in the case when they were installed......

From my experience they will not survive the removal process.
The seal is replaceable however. A good chemical flushing to remove oil, a liberal smearing of sealant (Right Stuff) around the bearing and a new seal may end the leakage.

A PO had installed these support bearings in my car. They work great in providing additional support to the axle shaft, but probably aren't needed unless the standard bearing has a bit too much play (not way too much play). My bearings leaked. I did some research and found that they are meant to be installed with an anaerobic sealer so I removed mine and used that type of sealer. Still had some leaks so I took them out and replaced them with standard seals and haven't had a leak issue since then.
Taking them out. Major PITA. Especially the drivers side bearing. I used a thin putty knife (handle removed) and wedged it between the case housing and the bearing. I then used a long screw driver (handle removed again) and drove that between the bearing and the putty knife. This was done to prevent damage to the trans case. Wedging a hard object between the bearing and the soft aluminum case would certainly gouge the trans case. I had to work side to side and around the bearing to get it come off. I think that they really weren't meant to be removed. The bearing is pretty much a solid chunk of steel with inner roller bearings. I reinstalled them and they worked fine ... no damage, but the leak came back eventually. I had to do the same process again to get them out. I will probably never install a set again as I don't like oil leaks.
My leaks were a few drips or a small puddle about 3-4" in diameter ... not that much. If the car in question is dumping a large amount of oil then I suspect that the seal on the bearing is gone or severely damaged. You can replace that seal without removing the bearing. I'd try that first to avoid what I described above to remove the bearing.
I've spoken to people that have not had any issues with leaky support bearings, but there are several threads on this forum from those that have had issues.

Well it worked out, the seal was an off brand and looked like the bearing support seal, but was just a seal, so it came right out, all went smooth, she is happy.
Just an update to close the thread.
