The MR2T tranny "short axel" solution, For those that want to know... Options

The cross member is the same on all 6th gens.

The front engine mount is the same on all 6th gens.

I've yet to find a difference between the GT and 205 passenger side mount. Maybe the rubber compand in the mount is stronger, but I couldn't tell a difference.

I'm running the full spacer - no problems.

Which side/sides are you running the spacer?

[scothaniel]

Only passenger side has the spacer.

[toyotacrazy]

Im going to use the old "spacer" from the mr2 axles Im getting. I will use this on the passenger side of my celica. From what Im hearing it should be ok. On the drivers side however, Im going to take the st185 inner that Im not using and have a maching shop cut it so I can use it as a spacer. The spacer will be less than a 1/2 inch, since the axle partially slides into the stub section. I dont see this to be an issue since people arent using spacers on the drivers side and reporting no problems. Ill post back when I get the axles and everything together. Which may be a while. later

Ok so I just got my mr2 turbo transmission in my car and took it for a spin today. There is a loud grumbling noise/vibration on acceleration and decel. only. Im feeling like its drive axles, but I had them apart and lubricated them and they looked fine. On the driveres side I did use the mr2 inner space and boot assembly. But I used the mr2 inner shaft that goes into the transmission. I used a full spacer (OEM axle spacer) on the passenger side. I didnt use one on the driver side. When I have the front jacked up and spin the wheels the side Im turning spins ok. The other side doesnt move unless I go to the other side and move it by hand. Everthing seems in place and tight. With the car on the ground the axles look straight. I used the st205 rear and drivers motor mounts. Any ideas what may be wrong?????? Thanks
I think my problem is the axle spacer is too long. With the car jacked up and spinning the wheels the drivers side spins freely. The pass. side axle binds when spining it. Also you can watch the engine rock when spinning the passenger wheel. Im going to get a 1/2 inch spacer in the pass. axle and let you know what happens. later.

You have to do this.

I used a full spacer (OEM axle spacer) on the passenger side. I didnt use one on the driver side.

When you say you used 1, do you mean +1. The axle stock has one of these already in it, and when you say you used a spacer, I think you now have 2 of these in it. Correct? My passenger side has 1 1/2.

When I have the front jacked up and spin the wheels the side Im turning spins ok. The other side doesnt move unless I go to the other side and move it by hand.

This is normal. Spinning one wheel and having the other move is not an accurate test for LSD as this sort of thing will happen.

With the full spacer in, can you turn the steering wheel side to side without it binding or resisting?

As long as axles can properly depress for turns, and the axle isn't forcing the wheel out of alignment, it shouldn't be a problem. As I said before, I'm using the full cage (spacer) on my car without issue. But who knows, maybe I'm just special.

Do have the proper outer axle for your hubs? (abs axle with abs hubs)

Also you can watch the engine rock when spinning the passenger wheel

Yeah, the stock mounts suck - even the 205's.

Yes I got the axle in with 2 OEM spacers. And drove the car. I unbolted the lower ball joint with the 2 nuts and 1 bolt then I slide the axle into place. Today I made 3 spacers all different sizes so I can hopefully get it back on the road tonight. Any suggestions what size I need? Thanks for the interest!

I got my car on the road again!
Ok heres what I used. I have a 91 mr2 turbo vsld.(Im pretty sure its vlsd) I used st205 shift cables, st205 rear and drivers motor mounts and brackets. I have mr2 inner axle stubs and extension shaft. I also have st185 axles. I didnt use any spacers on the drivers side. Just the hybrid mr2 inner and 185 outer. On the passenger side I took an oem spacer and cut it about 9/16" wide. I used the end that will slide into the mr2 extension shaft. To do this I put the spacer on a brake lathe and cut a guide groove. Then used a cut off wheel from harbor freight (replaced wheel with a better one) And 20-25 minutes later I was through the spacer. I put it back on the lathe and cleaned it up, onto the wire wheel for a finishing touch and your done!
The initial spacers being full width and using 2 of them is too wide for my car. It was binding the axle joint. I dont understand why some people use no spacers, some use thinner spacers and others use 2 full spacers and are just fine. Im wondering if the difference is in the different years/transmissions/differentials and depending on the passenger side extension shaft???? Maybe if we keep this thread going we can find out some answers. I hope this helps someone.

Hey guys i'm having the short axle problem since i lowered the car with eibach springs and i'm sitting on 18's. Do you guys have extra 10mmx1.5x90mm socket head bolts that you can sell to me? because i can't find them anywhere in my country and i need to extend this axle as it has sliped out on me twice. Also i think that the few of you who tried using the full spacer and are having lenth issues, didnot line-up the grooves so the knuckle and bearings can move from one spacer to the other freely. If you jam by having a ridge stop the bearings, then your overall axle will be too long.

Hey,
If you line up the spacer with the other one, the joint will fall apart. Im using a little bigger than 1/2" spacer and it works fine. I have a little bit of a whining noise when on the throttle. Im going to try a smaller spacer.
As for the bolts, I have some 10mmx1.5x90mm. How many do you need? Ill sell them for $1.00 each + shipping. PM me if your interested.

[1900]

thanks guys for all your help, especially toyotacrazy. i cut down the oem spacer to 9/16" and that worked just fine. i am also thinking of cutting down another spacer to 3/4" and trying it on because my camber looks a little off as compared to the left wheel. thanks again guys this really helped me.

Glad to help. It was just trial and error for me.

Okay, I guess I'm not special.

Last weekend I snapped the passenger side axle. I was driving around a corner and punched it, and soon as the boost hit I heard a loud bang and the car just glided to a stop. Funny how the MR2's stock LSD diff is worthless when the drive side is broken.

A quick tow home and some investigating revealed that the axle binds when turning right and the wheel is fully extended (as in a slight jump). I guess I was lucky though, I drove with the full space for a while with no issues until this.



BTW - here's another thought on this subject:

Before it broke. If you put the car on jack stands and tried spinning the right front wheel, did it bind or feel like the other side? You would probably be ok with a smaller spacer. (1/2") Thats what Im running on.

[scothaniel]

I did have it up on jacks, and it seamed to be fine. No binding, and the axle had enough space to compress/extend. It's just at this one point where it locked up. I've already replaced it and I'll just be cautious around corners until I can try a smaller spacer, or a different axle combo.

[Supersprynt]

I also had to cut my spacer down because I couldnt even get a whole one in the hub. I think I'm running 1/2 a spacer right now, but still get some noises. My carrier bearing doesn't line up perfectly for some reason I think this is the cause.

[scothaniel]

Do you have limited slip? Perhaps your one of the unlucky few who needs the exact matching stub: http://www.mr2board.com/forums/turbo-3s-gt...-lsd-stubs.html

[Supersprynt]

I have TRD, so it would use non-lsd axles.

Is it a high pitch whinning sound on acceleration?

[Supersprynt]

No, its pertty difficult for me to describe. I have one sound that sounds like the dust plate is scraping my rotor when I turn one direction, but can't find any evidence of it. The other constant one sounds like what I could only describe as ball bearings without lubrication. My first thought was CV joints but I packed that CV with grease after I took it apart and I don't think the bearings in the CV move like that.

IDK if anybody can relate to hearing noises you know aren't supposed to be there and not being able to locate.
