Maybe, because the optima is a deep cycle battery (i think) you could probably make it as long as you didn't tax the electrical system too much i.e. not to many stops and starts. If it's mostly highway then I'd give it a go. Would suck to get stranded though...

My code is 32--Vehicle speed sensor 1, so it wasn't the solenoid like I thought. I did however notice that even though I had tightened the bolts holding the carrier bearing it was still loose. I just did a quick fix and added some spacers to the bolts and that seems to have done the trick, no more knocking, but I do have some TB, the car will shudder when I turn hard right or left. It's not a real severe shudder but you do notice it. I am going to change the filter on the tranny to see if that helps. Eventually I'll go ahead and rebuild the torque transfer unit but for now it's ok.

OK, so the carrier bearing wasn't the problem!! After driving it today it still has a shudder. After a bunch of research I found that I might have a transfer clutch solenoid problem causing TB. I found some post about the Blinking "power" light and how it will tell you what the problem is. I have noticed the power light blinking at startup but until now I didn't know what it was for. I will check the codes today. How difficult is it to change a solenoid? And if I were to have it done what an I looking at as far as price? old post: http://www.ultimatesubaru.org/forum/showthread.php?t=102596

Nope, but I'll be using the wealth of knowledge here on this board many times in the future.

Well it looks like i found the problem:banana:, I got up under the car and found the the bracket supporting output shaft carrier bearing was loose, tightened it up and everything is good. I was freekin out thinking I was going to have to drop $1,000-2,000 bucks, so to only have to tighten a couple bolts is sweet.

Hi all, New to the site and needing some help. I recently purchased a 1994 Legacy wagon, automatic, AWD with 128,000mi. When I test drove the car I could tell there was a small vibration when turning hard left and accelerating but it was minor and I felt like it was just TB. However after driving 200mi back home I noticed the vibration was getting worse, and getting worse very quickly. The vibration is definitely coming from the passenger side front area and it seems to be concentrated around the center differential. The vibration is NOT felt in the steering wheel but in the seat and feet of the car. As stated before the vibration only happened when turning hard left and accelerating, now it does it turning either left or right both under load and decelerating, also starting to feel it when going straight but does not seem noticeable at speeds over 30mph. When accelerating hard and turning the vibration gets worse and you can hear an audible knock, not a "clicking" like a CV but more of a knock. Also sometimes when I hit a hard bump I can hear a clunk but it doesn't do it all the time. I have been doing a lot of research trying to narrow down the cause but I'm still unsure. One thing I am sure of is it's not TB. The passenger side CV assembly has been replaced and I have checked the sway-bar and tie rods and both seem fine, will be checking the wheel bearings tomorrow. I'm really hopeful it's not the diff or the tranny but my options are dwindling. I have tried placing a fuse in the FWD and the vibration is still there. All fluids are full and the tranny fluid does not smell burnt. The tires are all the same brand and size and all are wearing evenly as far as I can tell. Sorry for the long post, it's hard to describe car sounds/feelings over the net. Any help would be great.
