Strange vibration 98 OBS

Featured Replies

So a few days ago my impreza OBS developed a strange vibration. When I accelerate in 1st gear it will developed a low tone vibration that last for a few seconds then it stops. I then shift to 2nd and it will sometimes do it again lasting just a few seconds. I did install new empi axles about a month ago but up until no it seemed to drive fine. Any ideas on what I should start to look at? I thought it could be a cv joint but I'm kinda doubting it since it only last such a short time.

This is what the transmission mount looks like on my 98 OBS is there supposed to be a gap like that? Both sides look like this and the rubber will crumble a little when poked at. Im trying to figure out the wierd vibration im getting. checked the driveline it seems fine no play in the jounts that I could detect.

That looks normal to me. It is shaped like that incase the mount fails your tranny doesnt drag on the floor. This old it has probably seperated and could use a replacement.

 

I am going with driveshaft. Your going to have to drop it and check the joints that way to see if they have play or are seixed.

Ok im really hoping its not the driveline thats alot of cash to get a new one and I have never found an outback sport in the local pick n pulls. Ill wait until the weekend and pull off the driveline and check it out. Im thinking a fluid change in the trans wouldnt hurt either. I am also wondering if one if the new empi axles could be bad its been a month driving on them and just a few days ago the car started its issues.

Thanks for that link thats a really cool site. I really wish i had a shop so I didn't have to plan every repair in between weather. Apartment life sucks for working on cars haha.

i dont have one either, so i'm just about in the same boat. This is a straight forward repair however if this is what it is.
