Have grand caravan 2001 awd i get to 50 it starts vibrates think it might be carrier bearing after 50 it seems to lessen some no problem in front end what do u think

Hi, you could check your engine mounts.

90% of front suspension noise on caravans is sway bar bushings and sway bar links.Next is upper strut bearings.

I'd have to check your suspension. You think the tires are ok? Did you try rotating the tires to see if it made any difference?

I had the same problem with my 2001 grand caravan and had to replace the rear wiper motor,

Unit bearing is bad on one side or another. You have to raise the front of the vehicle, remove the wheels, calipers, rotors, everything down to the unit bearing. Turn both carefully by hand and you should be able to tell which one is bad.

jack it up put on jack stands and start put in gear and see if front tires are moving

Greg,
Sounds like wheel bearing issues. I've had my front wheel bearings replaced twice on an 02 Vue AWD V-6. The 02-07 Vues use the same wheel bearings and they are a known issue with these
cars. Another problem with these cars is the rear support bearing for the drive shaft in the AWD models. I recommend having the wheel bearings and rear carrier bearing checked out. Good luck.

Me too i think it a cv joint problem a cv joint got 3 rond bearing when turning each rond ball goes in a chanel it spin in there sometime that chanel get damaged a little hole appear and in occasion the ball get stuck in that hole and that your bad vibration i gave you example

Yes it's a bad seal and most likely the side bearing to the trans axle is bad too. Once the bearing has play, it vibrates and causes the oil to leak though the seal. Note: if one side went bad the other side is soon to follow since they have the same amount of miles on them. Might as well change both side. Good luck and hope this helps. Keep an eye on the transmission fluid level, don't want to burn out the transmission.

Your front struts may be bad,There is a rubber seat at the top of the strut that can start to bind while driving and turning. Replace struts and realign front end.
