Looking for a place that might do a good rebuild on my '98 5 speed.

 

Background: The original trans started to sound like it had rocks in it, anytime the input shaft was rotating. This led me to believe that there is a bearing going bad on the input shaft. Took the trans out, and put in a used one, which fixed the noise problem.

 

It also fixed some of the slop I was experiencing, but the slop has returned. I can be going about 25-30mph in 3rd gear, on the brink of engine braking down a hill, and the car will bounce between positive and negative loading of the driveline. This makes is very annoying to drive. There is more slop in my Legacy driveline right now, than the 4 speed Brat I've been driving around lately. So I want to get this fixed, and suspect the slop is in the trans.

 

Only other option possible option is the rear driveshaft & diff, but I don't see how that would be causing this.

Your bouncing slop is not in the transmission - it simply cannot cause that.

 

It's mounts - engine, transmission, rear diff, etc.

If you end up needing more info on a place to get a trans done in the denver area shoot me a pm and maybe I can point you in the right direction.

They are all STI group N mounts, with no more than 50k miles on them(I don't remember the mileage I replaced them at, but 50k is an aggressive estimate). The rear diff mounts were replaced less than 10k ago, but I don't recall what they are(but they are the poly bushings, not factory rubber). And when I replaced the mounts, it certainly made the slop go away significantly(wasn't nearly as bad then as it is not), but not completely.

Still - there is nothing in the transmission that can cause that kind of a problem. If there were enough slop to cause that - gear lash, etc - you would hear it and it probably wouldn't last a mile on the freeway before locking up.

 

There is NOTHING in a transmission that can cause that. The tollerances are to the .001" and you would hear a problem long before it got to the point that it would cause noticeable driveability issues.

 

Did you change the dog-bone as well?

No, I did not change the dog bone. I fail to see how that can cause any issue in this, since the issue changed when the transmission changed, and has since returned in greater amplification.

Well - I don't know what to tell you other than changing the transmission just because you *think* it's the issue is the wrong way to go about diagnosing the problem. Shotgunning parts at the thing till it stops is both expensive and not very fun. I think first you should verify that the drivetrain isn't moving as a unit before throwing a transmission at it...... again if the transmission had enough play in it to cause a noticeable bucking of the car like that it would be VERY loud. I've had a fair number of Subaru transaxles torn down and seen my share of failures as well - none of them ever involved anything like you describe and some had 1/4" of slop in the input shaft bearings.....
