Boringchuck Posted Saturday at 03:17 AM Share Posted Saturday at 03:17 AM 2000 Outback 130k new to me. It didn't have vibration when I boguht it 500 miles ago, now it does. It feels like judder from 25-35, but there's also vibration at highway speeds.Also, it lightly 'clunks' (that I can feel more than hear) when the gas pedal is let off of then put back on. The highway vibration is getting worse. I added the magic goo (Lubegard 19610 Instant Shudder Fix) to the tranny 100 miles ago - no improvement in the vibration from 25-35 mph. I'm thinking it may be the driveshaft carrier bearing or its rubber mount (but 130k is kinda low for that I'd think). My question is: how to diagnose that without pulling the driveshaft. I had the car up and crawled under and pushed up and down on the driveshaft and it moved rather easily - I don't know if the rubber mount should alllow easy movement or if it should be stiffer, it just seemed rather soft to me. The tranny mount just got replaced by a competent mcechanic. Any see-through-brick-walls folk out ther who can diagnose from a distance? : -) Thanks!

lmdew Posted Saturday at 06:11 AM Share Posted Saturday at 06:11 AM Put the FWD fuse in and see if it makes a difference. Link to comment Share on other sites More sharing options...
el_freddo Posted yesterday at 12:17 AM Share Posted yesterday at 12:17 AM Check your tyres for a bubble or something odd. I went through a process of eliminating parts from the back of my L series including removing the rear diff and driveshafts! Turned out one rear wheel developed a small bubble/egg on one side of the tread. Swapped the wheel and happy days! Link to comment Share on other sites More sharing options...
brus brother Posted yesterday at 04:38 AM Share Posted yesterday at 04:38 AM Do you feel it under the seat when the vibration occurs. Something similar in mine turned out to be drive shaft. Got an aftermarket since the u-joint was not replaceable and all was good. Link to comment Share on other sites More sharing options...
el_freddo Posted 15 hours ago Share Posted 15 hours ago Forgot to mention checking your wheel nuts are done up tight. This is a quick and easy check that could save a lot of headache! Link to comment Share on other sites More sharing options...
forester2002s Posted 1 hour ago Share Posted 1 hour ago I think that you are right to suspect the drive-shaft. The drive-shaft shouldn't be able to be moved by hand. It should be rigid, not soft - especially in the radial direction. A passenger in the back seat might be able to tell where the vibration originates.
