Question about 1999 Subaru Forester

1 Answer

1999 Subaru Forester has developed a shake when accelerating, esp. between 20-30 mph. Wheel bearings replaced - didn't help. Tires checked, balanced, etc. - didn't help. Front end allignment - didn't help. Feels like a drive shaft or u-joints, but I don't know if these cars even have such things. Any ideas???

    The shaking only occurs when accelerating and is much more pronounced when under greater stress (going up a hill, fast acceleration, etc.). Just cruising along (at any speed) the shake isn't felt. Any more thoughts. The transmission has been serviced resently, don't think its the problem.

Auto or 5-speed?
Subarus have CV axles in front and back. And a drive shaft from the center differential of the transmission to the back differential.

Yes, it could be the drive shaft or axle. If you turn the car hard left or right do you hear any noises - usually a 'clicking' sound? This is likely a CV axle in front.

Check the fluid in the transmission (Automatic) (info is in the Owner's Manual) to make sure it's full and/or gear oil in the front differential.

If it's an Automatic transmission, the fluid may need changed - NOT FLUSHED - if it has more than 30K miles since last changed.

06 Murano steering shakes when accelerating around 60 mph. Just balanced tires, still shakes. Doesn't shake while coasting same speed

Do you feel the shaking in the steering wheel as well? If so, it may be a worn steering linkage. If not, have your CV joints and U-Joints checked and, if you have a 4WD, have the transfer case output shaft bearing checked.

On 98 caravan 2.4 it starts to wobble at 40up to 50 mph mostly when accelerating when speed reached smoths also smooths out after 50 mph alll new including valves. could bad wires cause this?

How old are the good tires? These speeds usually mean belt or balance problem with tires...If new tires, they need to be re-checked for balance...and not out of round...also check for bent wheel...due to chuckhole? Sometimes a bent steel wheel can be hammered straight...hope this helps.

Cx-9 with 59,000 miles just serviced vibrates and shakes terribly when accelerating between 45-55 mph in gear 5 especially

It sounds like your some of your tire balance weights might have come undone, meaning you need to have your tires balanced. Or there may be a more serious problem with a tie rod end being wore out, or a ball joint or possibly wheel bearing. The wheel bearing would be accompanied by a whining, or howling. I'd steer toward a tie rod, or out of balance tire and wheel. Hope this helps!

Car starts shaking 40 mph

Replace the ball joints and/or rod ends.

Forester sounds like driving over rumble strips at 60/70 MPH

When the tires were balanced, were they checked for smooth tread ?
If they were on the back for an extended period of time, the tread could be choppy or uneven.

My 1999 Forester Subaru wheel bearings are bad both rear wheels not to mention the front I just had repaired at Firestone for 600.00 Is it worth the extra money to take the car to Subaru, a 300....

Are you sure that they bearings are really bad, bad tires can also give you a growl noise from the bearings if they are different or worn badly. It should not mater where you take it to have them done, just that they use good quality parts and replace them properly. Hope this helps and have a good day.

Drivers front wheel shakes at 30 to 40 mph and on turns but the shaking stops when vehicle is accelerated. What repairs or adjustments are needed to end "shake, rattle and roll"

Please have the balance of your tires checked. You may also have a ply fault inone of your tires.

Subaru vibration

I had similar problem with my '99 outback. Replaced the front half shafts and seemed much better. A few months later seemed to be comming back so replaced the driver side shaft again and the problem disappeared. I had put in rebuilt shafts and the driver side shaft was not rebuilt correctly.

I would not recommend driving it like this. Take it into a shop, most shops provide a free inspection.
