Project SC300 Road Racer: Part 22 – I Missed Winter…
Really large vintage, well worn, and well used lathe
And, in case things are really bad, CV Source has the right tools for the job. This lathe has been around for a while, and its operators are talented.

They’ve also got a media blasting cabinet, several welders, and all manner of other fabrication tools to repair and restore your components.

Sticking with the “right tools for the job” theme, a giant press is the right tool for both extracting the old wheel bearings and for pressing in the new wheel bearings.


Inside of wheel hub full of greasy gunk
Remember all that gunk on the ABS sensor?

Well, here’s where it came from — the inside of the front wheel hubs. I’m pretty sure things aren’t supposed to look like that.


Clean and freshly painted knuckle with shiny new bearing sticking out of hole ready to be pressed in
After CV source completely tore down the knuckle, they media blasted it, and then gave it a quick once over with spray paint to brighten it up and prevent surface oxidation.

Here is one of them ready to receive its bearing with a trip to the press.

Here’s a look at the disassembled outer portion of the axle’s CV.

CV Source spent a ton of time cleaning up all of the surfaces in here with various tools. It’s now so fresh and so clean and so ready to get full of grease and balls and… ok that’s getting weird.


  1. I would add one thing about bumpsteer. I learned a lot about bumpsteer on a wet AutoX track (the hard way), that I had no idea was happening in the dry. (The bumpsteer came from swapping Upper Control Arms on a EG6 Civic from Driver/Passenger sides in an effort to increase Caster, which is a horrible idea, and totally creates massive bumpsteer.)

    If you can drive under wet conditions in a wide open parking lot with cones (ideally, not during an AutoX), I would highly recommend that you do it. Because, dry tracks can mask a lot of ‘issues’ that only reveal themselves under non-ideal, slippery driving conditions. Anyway, it’s better to learn about the effects your suspension/handling adjustments in a controlled environment, rather than during a race.

    Don’t be like me, and don’t learn the hard way. Just sayin’.

  2. Yes, they are good lug nuts but they are milled not forged, not a big difference in 304 stainless though. Even at 10$ the margins are pretty small, cost of production is something like 4.50 so once you get through tax and shipping the profits are like 1.25$ for the producer and 2.50$ for the dealer. Really good lug nuts though, and way more concentric than forged and capped standard lug nuts, puts less stress on the rim.

  3. Stainless lugs nuts? Strange concept to me considering stainless is known for how easily it galls. Certainly not something I would think to put on a race car where the wheels and tires will be on and off frequently. Also, because race car wheels and tires are on and off so frequently corrosion is really a non-issue. I’ve always just gone for cheaper open ended hardened steel racing lugs.

    1. The MSI lug nuts have been in service on my Subaru BRZ since 2015. I have been using with Dorman wheel studs and have yet to run into any issues with them or my wheel studs. My BRZ has seen about 300 ish wheel changes in those 4 years due to it is an autocross car and I swap wheels at or before events and after.
      With that said i use a Beta Tools hardened impact socket and a Milwaukee Tool impact for every change. These lug nuts take a beating and look no worse for their time in service.

      I used to buy muteki SR48 lug nuts but I also had to replace the every year due to galling and they couldn’t handle the impact socket. This is part of reason why why the MSI lug nuts are hands down the best bang for the buck motorsports lug nut on the market.

    2. Stainless only galls on stainless, even then, only some grades of stainless. Stainless lug nuts on Steel studs with aluminium rims wont gall.
