4lug to 5lug conversion issue

Hopeful to upgrade for little cash, I have searched for a junk yard solution for the swap. I have read mjbobbitt's page and found that the bearings are not close enough for my taste :so. I have not found anyone who has addressed this issue. The use of the mustang bearing and the Ranger race does not allow the bearing to seat correctly in the race (it rides high). Does anyone know of a correct bearing and race combo that will work. I understand from reading that many kits are available, but I have blown alot of money already and am getting short fast. The Lincoln swap would be considered, but they have become very hard to find. Any and all help is welcome, new ground is not always easy to cover.

I had though I had seen a post on this before, but was unable to find it.

What year is your car? LX or GT?

Some cars will need to use the ranger rotors, some will need the lincoln rotors.
I got my kit from www.mpsautosalvage.com, they gave me everything I needed to make the swap, should give them a call, pretty sure they can help ya
This may be a little off point, but i did not want to start another thread. If I was to convert from a 4 lug to 5 would I be able to keep my rear drum brake (just to save some $$) or would I have to get the rear disc conversion as well?

I'm sure you know that front rotors are different on the 4 bangers

JnkYrdStang,
I looked at your profile and see you have a '82 GT. This being the case, you need the rotors from a '83-88 4 cyl. Ranger. Or you can pick up a set of '87-93 5.0L Mustang spindles and use the Lincoln/SVO rotors.

Cruisert,
Copied from the mjbobbit site:

To keep the stock rear wheel offset and drums, the '83-'92 Ranger/Bronco II Left (driver) side axle (29-5/32") from a 4cyl or 3.0L V-6 with the 7.5" rear end, or '86-'97 Aerostar RIGHT side axles (29-5/32") is what you want. They are the same rear axles, the center section is just on the opposite side when you compare the rear ends. The pumpkins are also off center unlike the Mustangs, so you will have to find two vehicles to pull axles from! You will need the drums from either of these vehicles also if you are staying with rear 9" drums. The 7.5 axle Rangers & Aerostars use 9" drums. These parts are direct 5 lug replacements for the stock 9" rear drums on the 79-93 Mustangs.

I have checked the part numbers of the bearings for the ranger swap and they are a different number. When compaired side by side (82 mustang set17 inner / set12 outer vs 83 ranger set6 inner / set2 outer), they are slightly different. The race outer diam. is different as well as the inne bearing race diam. The mustang bearing will fit in the ranger race, sorta, but it does not seat completely down in the race. I am sure going to the 87-93 spindles would be good, but I was looking at a one stop replacement with as little money out of pocket.

I will try to get some pictures to show what my delima is, I may just be being retarded about how the bearing rides in the race and it is not an issue at all, god knows it would not be the first time.

And you're positive you picked up the correct rotors?
Yes, I worked at Autozone for a few years. So looking up parts on the computer there was not an issue. Looking up the wheel bearings was my first thought, would not want to use old bearings in a project intended to go fast. I found that they are the same for all 83-93 Rangers even 4 cyl vs 6 cyl. The Mustang bearing is slightly larger than the Ranger bearing. It still sits in the race, but sticks up slightly. My concern is that the bearings will either wear prematurely do to lack of full contact with the roller surface or fail from uneven load stress.

I have never dealt with a swap like this before, as all my previous projects have been late 60's-early 70's cars. I know the complete spindle assy from a 70 Torino will fit a 73 Maverick for example, but that don't help much with a Fox Body....lol

Thats strange. Have you done any searching on the forums here for any ranger rotor swap threads? Surely this has been done or dealt with before.
I had found one while searching on google befor I joined this forum, however, I can not find it now. I am sure that one of the fine folks here have done the swap. I just have to find them. I will end up with the spindle swap, but I had hoped to get out cheap. Rotors are under $50 each, and bearings are under $20 per side. I hope someone that has done the swap will see the post and help. I would be ok if someone had done it and had no problem with bearing wear. I did send an email to mjbobbitt, but have not recieved a reply to my original question. I am going to continue to search for any info about the ranger swap. If anyone happens to find a post covering this, please link it..

Thanks in advance

I got bored the other day and did a search on here. One thread I came across said something about needing a different inner bearing, but didn't go as far as to say which one.
I tried looking as well, but of the ones I did find, sadly they did not cover my year. Now for the good news, I was searching e-bay and found someone selling a complete NEW conversion for 79-93 4-lug to 5-lug.
On 3 Performance LLC has a kit for $275 which includes drums, heavy duty axles and rotors, it does include $50 shipping from Ohio. I am going to contact them and see if everything is a direct fit with no major changes. From what I read, calipers and pads are the same as stock. As soon as I get a reply, I will post it just in case someone else runs into the same issue.

I do want to thank all of you who have commented and help motivate me to finding a solution. I think this ws a good idea to join THIS forum.
