'87 GT auto. I have to have my tranny seal replaced and am wondering if all I'll need for the job is the seal and replacement axle nut. Don't like surprises and would prefer to have all the parts on hand rather than tie the car up any longer than necessary. Where I come from Summer driving season is too short as it is. Thanks again for your knowledgeable advice. R
Grab the axle close to the trans. and push-pull to check how much play there is. A little bit is expected...maybe .050" or so. More than that means you have sloppy bearings. Replacing the seals will not fix the leaking if the bearings are bad.
Which side is leaking? The right side is the most common one. If that's the case, the bushing in the case that supports the differential carrier is likely worn. There is an aftermarket support bearing and seal kit that installs in place of the seal that has it's own needle bearing in it. Marc
Marc : It is the right side. Where can I get one of those units you posted about, might as well have all the parts bases covered prior to disassemble. One more thing ; what size, brand and how many bearings will I need? Is this a "major" project or equate to a simple axel replacement? Thanks for the help, R
I still have one on the shelf. 15.00 + whatever a small flat rate box costs. Almost as easy to install as just replacing the axle seal. Remove the axle, remove the seal, install the new integrated seal/bearing assembly where you removed the old seal, and install the hardened race on the axle shaft with the included loctite. It has complete instructions included. It is new but so old that the instructions are only in one language! Hope you don't need an interpreter. Marc
Marc: I'm just a good 'ol boy from the north and yankee is all I understand. Please e-mail all I need to know to purchase the part, rather buy from a member than any other source. rpyrazoo@aol.com Thanks, R
Sounds like language won't be a problem. I'm in northern Appalachia, so we just talk with more of a hillbilly drawl. When the Post Office opens, I'll walk across the street and see what the postage is. I will email you later. Marc
Marc: No. PM me through this forum with your payment total and method. My zip is 14218. We are hearing rumors that something called the "Pony Express" will be available within the next decade! Great to be part of the New Frontier. R
The GM 125C 3 speed automatic uses the 75125LRB axle stabilizer bearing. It fits either side. The replacement seal for the bearing is TC-1.375. The bearing driver tool is T404-303. I bought the driver tool, because changing the seal/bearing in the car is not as easy as if you have it out of the vehicle. Wanted to lessen my chances of error. Worked out well.
The Fiero Store sells these axle stabilizer bearings and seals: https://www.fierostore.com/...20BEARINGS&d=373&p=1 They're kind of pricey $170 for a pair, and they appear to fit both manual and automatic, and all years. Does that make sense? Are there alternative bearing/seal combos?
I have a leak in my driver's side seal and a seep in my passenger's side seal. Since the transmission fluid is also a bit burned I'm looking at whatever I can do to extend the lifetime of my (Isuzu 5 speed) transmission (88 2.5L).
I don't have any answers yet but when I know more I'll pass it on. These guys I'm dealing with are real pros, so I'll pass on your questions to them and attempt to answer as many as I can. R
