Shakes or vibrates

Thanks everyone but it ended up being a slightly bent front wheel.

The engine seems to be missing and when it shifts into lock up it vibrates. When connected to the computer analyzer we are unable to down load the troubles

Thanks Roy
Yes the codes are not coming through at all. Could that indicate a faulty computer?
Thanks again

Sporadically my 97 Dodge Ram 1500 4x4 will make somewhat of a groaning noise from the front end, and sometimes a vibration will accompany it that I can feel through the floor or pedals. Sometimes they occur together and other times either one may occur on their own. As I said, these are sporadic and not continuous, regardless of speed, turning, temperatuce, etc. Any thoughts or ideas as to what it could be? I've been reluctant to take it to a shop because the symptoms aren't constant. Thanks.

The truck doesn't have an anti-lock braking system. I took it in to a mechanic for inspection and they couldn't find anything wrong with it when it was up on the rack and ran it up. Checked U-joints and such. Had it out for a test drive and couldn't get the truck to duplicate the noise or vibration. To me it now seems to be driving rough, though that is hard to describe exactly what I mean. Not saying I blame the shop, just that maybe things are getting worse.

Hello I have a 97 ram 5.9l and lately it has been vibrating at low rpms and today it got really bad and the whole truck is vibrating like crazy u can see the egnine bouncing up and down and when I shut it off the last time there was a small tink or clunk noise friend said it might have came from the pully system ac pully maybe? I have no clue where to start any tips would be appreciated thnxs.

Could have one or more bushings worn out on the engine cradle giving the engine some free play to bounce around.
