Spindle options?

Post by wbaker01 on Wed Jan 11, 2017 8:40 pm

Getting ready to reassemble the front suspension and finally took a good look at my spindles today. Other than being crusty nasty after 43 years, one has a decent groove where the wheel bearing/seal would ride.

Once again, I can't seem to find any stock replacement spindles (I don't want to go with a lowering spindle) and am wondering what my replacement options are for those who have researched this subject? I'm looking for a bolt in option preferrably..

Bill, I'm pretty sure the 70-81 Camaro is a bolt in match.. should be easy to find.

Thanks Joe..Looks like these models interchange - 1970-'79 Camaro, Firebird, 1975 Apollo, 1973-'77 Century, Chevelle, Cutlass, Grand Prix, Le Mans, Regal, Monte Carlo, El Camino/Sprint, 1975-'79 Nova, Omega, Skylark, Ventura, 1977-'79 Phoenix, 1976 Cadillac Seville with disc brakes (1977-'79 full-size Buick, Chevy, Olds and Pontiac models with 11-inch rotors will also fit).

Interesting to see how much mixing and matching GM used to do..

No problem. You should be able to locate one pretty easily. You might also try car-parts.com and do a quick search. Might find one local to you or most places ship. Good luck.

I've got an extra pair in good condition that I removed from a 76 Laguna. They are heavy so I'm sure shipping will be quite a bit. I'd take $75 for the pair plus whatever the shipping would be. If you just need one I could do $40. Let me know if you're interested.

Wait...before you do this...B body spindles work and they'll give you 12' brakes...

If you go to this website http://www.car-part.com/ and follow the promps and make sure you have selected Colorado, there are a few that I think might be close to you Bill. I entered 73 Camaro into the car field.

Thanks guys, I may have found a local set..

Would be curious about that B body spindle swap, is literally just the case of bolting in the spindle with no other mods (other than the rotors)?

Here's some pics of the spindles I have. One of them has some marks on it but the surface is smooth and the rotors spin freely.

Hey, can you measure from the center of the back of the spindle to where the tie rod connects? I forgot to measure mine before I got rid of them.

Some people claim there would be bump steer using B body spindles, but I have yet to find evidence of it. The Trans Am guys don't have a problem, haven't heard any problems on the 73-77 A body side. The 68-72's and G bodies have bump steer problems...with a different suspension, not the same as ours...

Not to make another thread I will ask here.
I was searching for additional pair of spindles for my 74 elco to cure my spoiled caliper stud threads in my right spindle and for big brakes to make in future. One day I got several junk spindles from different year camaros and b-body's, and junk because frankly speaking seller lied to me that all spindles were in good condition.


I think it is ?73-74 camaro? spindle as it looks like mine 74 elco spindle and have a deep valley going from spindle pin to upper ball joint and small outer bearing



75 camaro upper and different years b-bodies lower spindles



?75 camaro?, didn't have such valley, only flat surface going to upper ball joint, small outer bearing


B-body with ABS, big outer bearing


B-body without ABS, big outer bearing


?78 camaro?, big outer bearing



After examining everything I found that distance from upper to lower ball joint is the same.
Tie rod end hole on b-body (need to remember) is closer to the center of the car.
The most interesting thing for me is that the later year of Camaro spindle is - less cast metal is used to shape the spindle. All "meat" around ball joint holes, around tie rod hole, meat in the center section from pin to upper ball joint is weaker/less volume. And 78 camaro spindle that has less meat from all - got larger outer bearing.

Does anybody knows what is the reason of GM to use less metal in modern spindles and changing to bigger bearing the same time? Lighter engines? Improving factory design? More strenght castings? Anything else...?
B-body spindles has nearly the same meat as 73-74 older camaro spindles.

I would like to use 78 camaro rusty spindles to make a big brake kit cutting away stock calipers mounts etc, and I wonder does 78 camaro spindle has the same strength as 73-74?
Or it's better to find good B-body spindle set to start with cutting...

During the time these cars were being built, the USA was still reeling from the OPEC embargo. There were cars lined up for fuel for hours because fuel ran out at the station while the embargo was in effect. The government also started requiring emission, safety, and fuel mileage improvements. Add to that the competition from foreign makes that got great fuel mileage cutting into the market.

The result is stuff like this. Lighter castings to help shave weight. As you can see, the thicker parts are where the weight of the car is directly supported by this part. I believe the older parts were built with overkill in mind to compensate for variance in quality, clearances, etc., because there was no real pressure to make them better. But as time progressed, regulation and market pressure forced them to be more efficient in the use of raw material.

As to the big bearing/small bearing issue, I don't know what made them use one over the other except for perhaps the options installed on the car.

If you are going to use factory parts for a big brake upgrade, I suggest using the B-body spindles. I don't know what your plan is to modify the Camaro spindles, but I get leery about messing with the strength part of a primary safety system.

I agree with bigredlaguna..I'm not sure that I would modify any factory suspension parts..After the time and effort I put into rebuilding the front suspension on my car (and I used stock parts). I'd have been ahead, time wise, to have bought after market suspension parts. Yes they are expensive but by the time I bought, cleaned, removed and installed ball joints/bushings, etc. It was a time consuming effort..

The spindles for our cars are hard/impossible to find. Mine needed way too much work to clean/restore so I bought a pair of 1970 Firebird spindles that had already been restored. Paid a fortune for shipping but they were in much better shape out of the box versus cleaning what I had.

A good part number manual(s) is also invaluable when you start looking to mix and match parts and are wondering what will work....

Good luck!

Nothing special about plans on bbk. As usual if going not floating calipers and more pistons some cutting is needed to fit bracket. Like with Wilwood or Kore3 setups.



Outside of US the chance to find mint used pair of spindles is going to 0 I think Very Happy On my example, from 7 spindles I got only 3 good condition at first look but all are from different years.
Am I right that there is NO aftermarket spindle's pin replacement part? I googled much and can't find anything. Very sad that castings are ok but you can do nothing with pin.

Are the B-body spindles a direct bolt in? What year B-body would work?

That’s really odd the pin would be replaced.

YES. They’re a direct bolt in. No modification or change of suspension geometry.

77-96. Be aware the 95.5 and up Impala SS and Caprice 9C1 use a 5/8 ball joint. Grab a pair off a regular Caprice, Fleetwood, or Roadmaster wagon or sedan, and you'll be good to go. In order to keep your bolt pattern you must either redrill the holes to 4.75x5 or use 89-91 F-Body WITH PERFORMANCE PACKAGE rotors.

How do you redrill the bolt holes you ask? This tool is really inexpensive if you're considering an Impala SS rear axle.

When I did that exact swap, my wheels were relocated inboard 1/4", so I needed to adjust toe-in.  Caster and camber were unaffected.

Was that the whole wheel or just the tie rod that is located inboard 1/4"?

I did it like 8 years ago, so memory is a bit fuzzy, but it was the entire wheel -- I remember being surprised about it and that I had to readjust toe-in. I used the standard 93 Caprice spindles.

I read on some forum that the hole wheel is inboard. I will try to compare my spindles.
