I have a 1994 Dynasty, and I would like to convert the front wheel bearings to the oil bath, wet type. I have no idea where to find parts, or what parts that it will require. I plan to have a local shop do the conversion, just would like to know what this consists of. Don`t want a bunch of stuff that isn`t needed. Thanks

A couple days ago a member posted a great write up of this conversion with a bunch of pics....trying to find it to post for you. It's a fairly simple process. Basically new bearings, seals and end cap...not rocket science at all.

I've mentioned this many times before on these forums. Consider using a semi-fluid grease such as Mobil SHC007 which is a synthetic. You get the benefits of an oil filled hub but not the worries of a leaking inner seal and soaked brake lining. Pack the bearings as normal, fill the inner cavity up even with the bottom of the opening and fill the oil hub cap to the full line. I was first introduced to this idea by the fleet maintenance people of a major southeastern trucking company.

Below is the link to the thread of DIY conversion of our 2000 Signature a couple weeks ago. The only parts you'll need are oil type innner seal, the new hub cab, and 2 qts of your favorite 75-90w.
Your coaches part #s are probably different than ours. Your favorite OTR truck parts store should be able to fix you up once you know your current bearing and seal part #s. Then they'll know exactly what you have so as to sell you the correct oil type seal and hub cap for the conversion.

X2 on the semi -syn grease, your wheel berring/ leaking oil seal worries will be over. I changed mine from oil bath to semi fluid grease 4 years ago and have had no need to remove them since. One note though the SSF grease is a bit of a challange to handle and not get it everywhere, and you need to make sure you use "Vented" caps on the covers, and you will still need oil bath seals. I run this set up in all of the non-driveing axles on medium and heavy trucks and trailers.
