Hey everybody!

I'm Cody. I hail from Flint, Michigan (1 hour north of Detroit). I'm quite the gearhead, but I have much to learn, especially about these here machines!

My car/project list is extensive. If you want to see any pictures, I'm happy to oblige! But for the record, I've got these machines (in age order):

1960 Chevrolet Corvair
1983 Oldsmobile Cutlass Calais Hurst/Olds
1984 VW Vanagon
1989 Volvo 245DL
1989 BMW 635csi
1990 VW Jetta Coupe VR6
1990 Ford Mustang LX 5.0 Hatch
2012 Ford Mustang V6
2013 VW Beetle Turbo

I'm actually about to get into Mitsubishi ownership for the first time! I've got a 1989 Dodge Colt Vista I'm picking up this week! I'll be trading my trusty Volvo for it. It's got some slick Nissan 280Z wheels on it, and come with a roof basket to boot. Pictures at the end of the post.

Main issue: it needs a transmission. It's a 5-speed car with a 2.0 G63B. What I've learned so far is that later transmissions (1G/2G Eclipse) should be bolt-in using the mounts from this transmission. However, I am trying to learn if I will need new axles or not. Trying to learn about what diameters are what when concerning these cars. Trying to also understand the length differences between generations. I'm willing to take my chances if I can't find the info I'm looking for, but I feel like you guys can help! I THINK that my axles should be the same as 1G FWD. My car is related to the Cordia/Tredia of the 1980s of course, I understand that. I'm not sure if there is stuff shared with the Colt hatchbacks, or if those are more closely related to the 1G Eclipse. Anyone else have some ideas?

Welcome!

That is, quite the list of cars you have going on there.

Wish I could add more to help with trans and axle situation, but I would suspect the following:

Early FWD transmissions may share center diff parts with the later 89+ generation, so if 100 series or 200+ series being a size split point, would mean you have 25 spline inner axle cups and possibly the same diff setup as KM210/W5M33/F5M33 type diffs. If you can confirm that, then you have all the axles you can shake a stick at, with regards to most if not all AWD products in that era; find the compressed axle length to suit your current parts in hand. Later 92.5+ especially in turbo FWD flavor, went to 27 splines due to torque increases at only 1-2 wheels versus splitting among the 4 with AWD. RockAuto carries tons of axle parts, so it would be best to start there and see if they list any axle information in terms of length and what not. Certain transmissions may have deeper/longer axle stubs, so pay careful attention to that detail. I wonder if some of the guys here will chime in with axle information and more cross over stuff. There is a van section here, and even a van forum on FB, dare I say it. haha Lots of our members here lead dual lives between FB and the site.

If you have your axles out and can measure and photo document them, any axle manufacturer that has an extensive list of products will be axle to match you up with a proper fitting part. EMPI, Cardone, SurTrack, Trakmotive, APWI, etc.

I'll link to a pic that RockAuto uses to help distinguish overall length, etc.

the most i know about ColtVista/VistaWagon axles is that the automatics and the manuals share the same axles, and one of the axles is specific to Colt Vista/Tredia/Cordia/Elantra, while the other one comes off just about any CSM product from 86 to 92, but it's been so long i can't remember which one is which.

Devolution,

This I have found in my research since my initial post here. Thanks for the confirmation and help!

Flying Eagle,

I ended up with a trans out of a '93 GST FWD. Therefore, 27 spline axles as I found out very quickly when the CSM axles didn't work. Ordered '93 DSM axles, and they fit the transmission perfectly, and slide into my spindles, however no matter how I searched, I could not find a set that were the right length. Eclipse FWD ones were closest, but are an inch too long.

The other issue is that the outer stubs, where they seal off to the spindle, are larger than the standard stubs from the CSM axles. Tried wheel seals from the DSM, and they're too large to fit the spindle opening. Tried having the old stubs swapped onto the new axles, and the driveshaft shop said they wouldn't match up well enough to be compatible. They also said they wouldn't shorten the shaft.

So, now I am looking for a shop that will not only shorten the axles, but effectively use part of the original CV shaft section and weld it and balance it onto the new shaft section at the correct original length to create some one-offs to fit my car, as it will get a 4G63T here soon. Just trying to make it all work in original form first!

yank the axles apart, you might be able to salvage the centre sections of the old axles and just replace the ends with the 27-spline stuff, repack them and put new boots on. not sure what the spline count is on the ends of the centre section though, i used to, but it's been a very long time since i took apart CSM axles.

Well, and this is what I had the local driveshaft shop check out between the pairs. They said that they were different enough either in size or spline count that it couldn't be done. That was my original, simplified route versus having a franken-axle made.

Rockauto sells axles for your exact model 1989 Dodge Colt Vista.
