I FOUND THE PROBLEM WITH THE DISC BRAKE SWAP!

Galaxie_406 · 01-22-2006, 07:34 PM

This swap situation with some guys being able to align the front ends and then other people having camber problems just bugged me to death trying to figure out what was wrong. Same part number on the donor spindles, basically the same cars, same taper. Could it be sloppy workmanship at the Factory? (maybe a little) but I don't think that was a major maybe just a minor contributing factor. BUT ALAST! I have found the problem! This will save you guys hours of grief and money! When you get your set of spindles I will tell you what to look for and the spindles to avoid so you WILL be able to align your car!

Nope, can't tell you in this posting. I want to keep you in suspense. At least tonight I will sleep peacefully.

Ah yes, good morning the birds are cheerping and the sun is shining and I have the information for you! (Drum Roll)

In my shop yesterday as I was working on 4 sets of disc brake conversion spindles I noticed that the upper reemed ball joint hole was NOT in the same place as some of the other spindles. Some of the holes were closer to the disc side and some closer to engine side as much as .100 almost an 1/8 on just the four I had. This may be a large factor as to why some people have $ucess and others having problems with their swap. I would suggest when looking for spindles that you inspect them prior to purchase and look for the spindles that have the hole drilled closer to the spindle end, this way when it comes to ajustment you won't have your wheels pointing out at the top.

Good stuff.... Thanks! I'll be going down that road in a few months - Unfortunatly, by then this little tidbit will have leaked out of my old feeble brain and I will not be able to find the thread.... But thanks!!! Really!

Im gonna have faith that mine are fine, and not worry till I get home to see..........wait................................. ..no, I'm a little worried now. Where did I put that bottle of TUMS ?????? AH, there it is!!!!

Great revolation Rattpac. But without looking at a room of spindles, what kind of measurements should i look for?

wayne64 · 01-23-2006, 06:26 PM

Makes sense Rattpac, and maybe the difference didn't mean much to the 74 and up since the top shaft attached differently than ours. I now have a stock 64 spindle on loan from a FM member and friend, and the local yards are geared up waiting on another donor set. I don't want to take my car down till I have a set reworked for a weekend swap. I just bought a power booster and master so I can stop alittle easier

If I get the spindle problem worked out then I'll be happy, at least for alittle while

To answer BoutTime64, from the looks of things measuring from upper ball joint hole (closest edge to outer casting) you really need a min of .300 thousanths of an inch. I have one set that measure .220 and I feel pretty positive that there could be a wide range of differences on the spindles. I have 2 more sets to clean and blast then I will also measure those and followup with the findings.

Galaxie_406 · 01-23-2006, 06:56 PM

If anybody is in a problem situation with spindles, I have access to a pretty good supply of California grown axles.

Phalanx · 01-23-2006, 07:31 PM

a picture is worth a thoulsand words, do you have a picture with two spindles side by side?

Galaxie_406 · 01-23-2006, 08:11 PM

No, but I will see about posting that tomorrow sometime.

trukstopcowboy · 01-23-2006, 10:29 PM

i think i know what u r saying, anytime you change spindles you need to do an alignment, and if you have a race setup you may need new springs due to the height you need it to be(where the lower arms are at... attaching point and ball joint level differences). i find even cars with eccentrics and no shims sometimes need to be shimmed. but i dont how the galaxies are adjusted unfortunately! but i want a darn 63-64 2dr! yee haw! camber curve

jakengle · 01-24-2006, 04:32 AM

Interesting find. It would be best to measure the location of the upper and lower ball joint holes in relation to some machined location on the spindle rather than measuring to an unmachined edge. The spindles may come from different casting molds and the thickness around the hole would vary.

I would take a straight edge and lay it across the machined area that the inner wheel bearing rests against and measure back to both the upper and lower ball joint locations.

Galaxie_406 · 01-24-2006, 08:24 AM

I agree that a casting is definetly not a perfect size and it may not be a bad idea to see if I can get this measurement from a couple different spindles.
Just wish I had a nickle for every time I have measured these things......
