Correct, the bearings don't completely fail. The get loose and must be replaced. The original '91 Corvette bearings which are now hard to find were far better than replacement bearings available now. Those bearings had much better seals. The bigger problem is the geometry of these bearings is...

Poor bearing life to me means 20 laps on a 2 mile road course. I'm not certain what the "failure mode" is, but I believe the bearing gets hot, the grease becomes to viscous for the (one lip) seal to hold, grease escapes and they burn up. The bearings are sealed from the factory. I plan to...

I road race a C-4 Corvette. They are notorious for poor wheel bearing life. I'm attempting to find a way to extend the life a little longer. I currently use NTN modular roller bearing assemblies in the rear hubs. Those bearings have a poorly designed seal. When the assembly gets hot from heavy...

Thank you for that information. I have to use a cooling system due to the high header heat in the transmission tunnel, so that restaint alone is reason enough to change the lubricant. Jerico recommends Mobil 1 - I should respect their recommendation if for no other reason than that's what...

I think you are probably correct. The box is old and provided years of dependable service in an environment it wasn't designed for. Jerico makes great products, so does Redline. My goal here is to understand the reasons why it failed. It would have been better in my opinion for Jerico to have...

Thanks. The vehicle is what used to be a 1991 C-4 Corvette. Not much of the orginal car is left. Just the body panels and most of the frame. It is a dedicated low budget racer but it's what I can afford.

I am using a drag box in a road race car. I have road raced with this box for over 10 years but didn't start using Redline until about 4 years back. I do not know what the gear material is, but know that they use different material in their road race units. I'm having a road race trans built...

I have a Jercio DR-4 in my road race car. I'm aware the drag box is made using a different gear hardening process and is not best suited to road racing. However I've road raced the car for years with Redline shockproof lightweight in trans without a problem until now. Several gears failed in the...
