Make sure the wheels are properly balanced and secure. Check all steering components and bushings for excessive play. Make sure steering box is secure on frame. If everything is tight, you can have alignment moved slightly more positive (caster only) and that too should help.
Wheel bearing hubs can also cause shake in certain cases and a binding brake caliper can as well (one wheel will be really hot after driving when compared with others) If shake is in body and not front end (you did not say) check driveshaft joints for play.

What is causing my 1995 Honda accord lx to shake bad after 50 mph. it was not doing it before, it's been doing it for a week and a half or so, any idea what might be causing this? thanx in advance


have a front end and suspension check for loose /worn ball joints , steering rod ball joints , failing wheel bearings
check tires for belt separation , bulges and other defects,including balance
check wheel alignment as it can be castor wobble cause from failing coil springs

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.

When van goes over 50 mph, van shake bad.


The best solution to your problem is to see if you need new rotors,brakes,shocks,and suspenion,rocker arms. I have a regency elite 98 oldsmobile that did the same thing.

1996 Ford explorer 6 cyl. shakes at 45-50 mph


If the engine is misfiring and that is the source of the shaking then the check engine light will be flashing like crazy, other wise it is not the engine causing this, I know was a Ford tech for 25 years.

At 40 mph the car starts to shake. It last to 5o


I have this same car with exactly the same problem. Begins shaking at 40mph and stops shaking as soon as you let off the gas, but then begins again as soon as you press on the gas and smooths out as you get over 50. And the shaking is not felt through the steering wheel. Solution: Replace the transmission mounts. There are two of them, one on each side mounted on the frame right next to the shock strut. There is also a front and rear engine mount, but I replaced the two as described and shaking is gone.

It sounds like you need a tune change at least the wires and plugs it also could be a worn or broke motor or tranny mount.
