Bubbajoe's project is now officially published! I know, I have a long way to go but with people like him building stuff like this it'll happen... He should make quite a few other publications as well.

I did get some work done though , started cutting out the frame rail to install the upper control arm and set one mount in place and welded it in there is more to do though the area where the mounts install will be renforced with 1/8 plate and also filled in with the same material

Quick question for you...........I see on page 29 that you say you are using a C5 bearing assembly at the rear.........by chance, do you know if the C5 and C4 rear bearing assys are dimensionally the same or different?
Would like to know because the C5 bearings seem to be a little more $pendy than the C4s
Thanks -- and I'll also add my voice to the many already spoken -- this is a fan-damn-tastic buildup thread!!!!!!!!!!!!!!!!!! Lots of good engineering going on inside here. And that is great to see

You missed it. Go back to page 29 and you'll see where he replaced the C5 rear bearing with an S10 bearing. Apparently, the C4 rear, 82-85 Eldorado front, and 4wd S10 front, bearings are all dimensionally identical. Not sure if the axle spline and diameters would be the same though.
You'll have some minor clearancing to do, but you can definitely use the more reasonably prices bearings.

Thanks for the response Todd.................just wanted to make sure that the bearing OD was the same between the C4 and the C5........ 3.60". At this point in my next project, I'm concerned with setting up the proper bearing and knuckle. In fact, the C4 bearing makes things easier for me

No problem, here some more from the other thread:
quote
Originally posted by gusshotrod: Just some info: C4 rear hubs are about .010 larger diameter than C5 front hubs where they center in the spindle. Both have a triple bolt pattern with the C4 about .3 larger circle. C4 rear hub has .75 more off set than the C5 front. You could mount the C4 hub into the C5 spindle by enlarging the ID of the spindle about .010 in. and slotting the mounting holes in the hubs. Neither item whould require a machine shop. You would end up with about .75 kingpin offset (good) and would be cheap. King pin angle looks like 8 degrees. Brand new aluminum spindle and hub with very good geometry for about $300
Bubbajoe has some info on this in this thread too, but I'm too lazy to sift through it and find it right now. There's just so many pages...

there is no need to enlarge the spindle center hole the C4 or S10 bearing fits right in no machining requiered but you must move the boltholes out 30 thou so you can bolt them in I have allready done this with my spindles and it works great as for the axles the s10 are way smaller than the C5 axles but the s10 CV's can be fitted to the fiero axles by swaping the drive cone with one from the early caddy FWD 86 as they fit right into the s10 axle CV and except the fiero axle spline
Are we sure the s10 and the C4 are the same bearing? The C4 bearing that I had would not fit and measured .010 larger than the C5. Also the bolt holes were more than .030 off. Anyone know the pt no forthe S10?

In the other thread it was the 82 Eldo front bearing and C4 that were determined to be identical. Same part number/same price, at Autozone or Eckler's. Timken part # is 513013
Sounds like the S10 bearing is different than the C4/Eldo bearing.

Well i'm confused. I've got an invoice and boxes for C4 corvette bearings from Eklers with the 513 pt no. which Todd says is the same as the Eldo and measures the same, neither of which fit the C5 spindle, and Bubba has an S10 hub which has the same diameter as the C5 hub and also has the 513 pt no. Whatever, it appears the S10 is cheaper and a better fit in th C5 spindle.

the part number for the vette is 513020 the S10 513013 but the S10 The Eldo and the C4 all have differant numbers according to Gm parts direct in the mitchels catalog

Great Information so far from all of you on this bearing discussion ............."+"'s for y'all...........
For those that have bought any of the following:
S10 front bearing C4 rear bearing C5 rear bearing -- think this is 3.60" -- can anyone confirm? Just making sure I have the right part Id'd in my head Pont. 6000 front bearing
...........can you post measurements of the bearing O.D.? It'd be a huge help to me and my custom spindle project, and it might help clear up some of the discrepancies and myths out there
thanks in advance,

I don't know why you got the information you did off the Autozine site Bubbajoe. Here's what I got a few minutes ago: Plus, the day I posted the specs in the other thread I had just went to "the Zone" and looked at the bearing. I forgot my caliper but eyeballed it with a pocket tape measure, and also saw the box and part number.
Edit - I just searched the Autozone site again for the Vette bearing and it does come up 513020 ($150), but as mentioned, gusshotrod purchased 513013 from Eckler's (a Corvette parts specialist) as a C4 rear bearing for $110. Autozone just doesn't realize yet that the 513013 can obviously be sold for the Vette.
As for GM Parts Direct - I'm not surprised that they would have different information/part numbers from the Timken aftermarket replacement piece.

I have access tp timkin and will check the number but the 513013 is the S10 bearing and is not the same as the vette 513020

It must be Autozone's site because I just got this for Bubbajoe's bearing: According to this they are indeed all the same. How you search their site must have some bearing - play on words intended - on the outcome.
I was reading this massive post, that you have here. On page 29 you were talking about a rear valance, under the rear bumper. Try using an 82 Trans Am wing. That is what I used when I made mine.

nice job I am using the gt wing for mine but yours does look great keep up the good work
The flange diameter we are concerned with isn't on your list Bubba. Dia for G is listed for the inner step on the s10/eldo/c4. We need the dia for the outer step, which is the one that locates into the C5 spindle.

OK gusshotrod the bearing is in front of me and i am going to measure each post pics and sizes this pic is of all parts upright vette bearing and S10 bearing as you can see the upright is un machined only the holes elongated vette bearing S10 bearng the S10 bearing only has antisieze on it to prevent it siezing in the bearing bore not real clear but it measures 3.605 vette measures 3.600 housing measures 3.610
