Rear differential? CV Axle? Somethings wrong...


Recommended Posts

Okay, I've crawled under, looked around, and I still cant figure anything out.

 

What its doing:

 

When I turn the car (either way) it seems like something is trying to lock up the right rear wheel. It's only the right side too, which is why i think it might be the axle...

 

I don't know how else t odescribe it. It's very obvious when your in the car, or outside looking at the wheel.

 

I don't want to tear into the rear diff just to have nothing wrong with it. I can't afford to mis-diagnose this one.

 

MY question is, does anyone know what (or where) my problem is? Feel free to ask me some more questions, and I'll answer them as best I can...

 

All help is appreciated. I already know this is gonna hurt the account...

Okay, well, Sorry I didnt back sooner, but anyway...

 

To answer your question, no it didn't surge forward after putting it in park.

 

But, I crawled under there and noticed that a nut had gone missing and that the bolt had almost fallen out. Got a replacement on that hoping that it was just putting stress on the axle or diff, but that didntr help at all.

 

So realizing this is a much bigger task then I'm able to undergo right now (small garage, VERY limited tools, and even less free time), I had AAA tow it to a shop nearby that always has signs outside for CV work.

 

I got a call back from them today saying that I need a new transmission, and that it'll cost $2500.

 

Yeah, not gonna do that. Doesn't make any sense to me how my trannny could be bad. Plus, the car was less than $2000

 

So I'm going to call anther shop my step dad knows and see if they are willing to take a look-sy.

 

Any other ideas as to what my problem is?

I had (have) a similar problem, the rear wheels, both sides, would skip when I made slow tught turns. It also jumped forward when I turned the car off, I didn't know the two things were related. I changed the rear diff with a known good spare and nothing changed. I heard about torque bind but didn't understand how it could make the rear axle act that way. There is an artical about torque bind at legacycentral.org. I tryed to copy/past the URL here but it didn't work. I put in a bottle of Lucas Trans stuff until I get better weather to fix it and it is "almost" not noticeable now. Gve the Lucas stuff a try for now.

Hmm, Might have to try the lucas stuff...

 

But with my car, it only "grabs" for lack of a better word on the passenger saide and it doesnt hop forward after placing it in park.

 

I just dont get it. My understanding about rear ends is very limited. Especially on subarus...Just kinda frustrating right now. Lots goin on, not lots o money (when is there these days?) and just makes me mad not knowing about what wrong with it.

 

Frustrating.

Let's start with something cheap and easy. Does your car have AT? If so, have you tried installing the FWD fuse? That will rule out torque binding from the transmision. It might also rule out the rear half axle since your car is in FWD. Raise the car and check the rear wheel for bearing play or noise, also cheap and easy. I wonder if it is possible to drop the rear axle and then briefly run the car? If the noise is still there without the axle, you're almost certain that it is the bearing. Rebuilt axle, about $60.00. Probably worth $60 to diagnose and possibly repair the problem.

The FWD fuse did not help me find the problem with torque bind. The fuse turns the duty solenoid on and off, this solenoid can be one of the problems that cause torque bind. I had to disconnect the drive shaft at the rear diff and drive in a circle in a parking lot (slow) to see the difference. Sometimes if you change this solenoid it fixes the problem (90-94). Or if you need a rear axle let me know, I have two good ones, $10 ea plus shipping.

Update here,

 

I went to pick up my car from the ahop, and asked a cuople of questions. He mechanic told me that there is a set of clutches inside the transmissions that are going bad. I was gonna haave it towed home, but he told me to just go ahead and drive it (less then 5 miles) and take the sharp corners easy. So I did, and in the sharp ones just threw it into neutral.

 

Anyways, after talking to him, I kinda believe him. Not sure my car is worth the money to put a new tranny in, though. If I did replace it, I still have to fix the wreck damage (another $700).

 

But, does the bad clutches make sense to anyone else, or does anyone have experience with them? I didn't know they were there, but I don't know much about awd.

 

As for this fuse, can I put it in and leave it in and drive it as FWD? The guy told me that MAYBE I could judt disconnect the drive shaft and put in a plug or something...? Would this work? kinda skeptical about it...

 

Thanks again,
