Let me rephrase that...
After J-body bearings. Next best possibility to swap into stock uprights for racing type use? Corvette stuff is pretty big....

C5/C6 Corvette hubs on custom uprights, not stock uprights.
The other idea involves modified stock uprights, but not C5/C6 Corvette hubs.[This message has been edited by Steven Snyder (edited 02-11-2015).]

I talked to my buddies with the J-body LeChump car. They DO run stuck front hubs (with custom knuckles and brakes). They can make them last for 24 hours, barely. They run street type tires. But 24 hours is a LONG time in normal road race terms.
I have to run stock knuckles, that's the reason for the question. J-body stuff does seem to be a reasonable option though.

24 hours is 6 weekends for me, or roughly one season. Good to know. Can I get in touch with them? I'm curious about lap times, specific tires used, alignment settings, brake pads, corner weights, etc., as these all have impacts on bearing longevity.
I'd also like to know why they made custom knuckles if they are using the stock hubs.. Usually brakes can just be adapted with add-on brackets.
Thanks again for the info![This message has been edited by Steven Snyder (edited 02-13-2015).]

I understand that the Arraut Motorsports (formerly Held) front lowering spindles use rear bearings, if this is true, then this upgrade could probably be utilized for the front of all cars 84-88, as they make drop spindles for all years. Probably slotting the cartridge holes would be all that is needed.

I haven't heard anything great about those spindles.

Damn, another reminder why Bloozberry was such an asset to the forum. 
Sorry Steven, not trying to hijack your thread. Just wish to show my appreciation to members here such as yourself who have so much to offer the Fiero community.[This message has been edited by Patrick (edited 03-02-2015).]

I have temporarily removed the drawing for the spacer. The spacers I made from the drawing fit the spare axle I have, but they did NOT sit flat on the axles on my car, which had a larger fillet radius. You would not be able to easily see that they weren't sitting flat unless you shine a light behind and look for a small gap. If you made spacers based on this drawing, please verify fitment, and grind the chafer larger until the spacers sit flush.

Cadillac Rear wheel/hub update to be used on the front of 88's: I decided to look into this. I've been to wrecking yards and the bearings I have found are all aftermarket. I took them apart and the reason you can not use them is that they all have a crush collar compressed around a lip at the end of an unthreaded shaft. You'd have to take a die grinder and cut parts off until the cap can be removed. The collar is on a lip instead of a threaded shaft. Hence the aftermarket unusability as previously stated. However, I did find one new bearing, made in the USA, that had been sitting on a shelf for a long, long time. It has the nut on the end of the shaft with a cotter pin, under the seal cap. The problem is its only ONE and they are all gone.
I eventually did find two US made New Old Stock Green RW402's. These are the specified 513009 bearing hubs made by Green in the USA. They disassemble and have the large castle nut. BUT, they will not work because the spindle is manufactured from the opposite side of the bearing. The spindle is made on the mount to the cadillac side not the hub side. Total bummer.
Additional note: 1984-1985 (non ABS) Corvette front wheel hubs are a direct bolt in for the Cadillac Seville. But I have not taken them apart to see if they have the same bearing dimensions as the rear Cadillac bearing/hubs. They are more readily available but the nonABS ones are hard to find.
Pretty close to a dead end.[This message has been edited by IXSLR8 (edited 04-12-2015).]
