I have a 2000 caliver when I put it in gear the motor rocks and makes a clunking noise

1 Check battery connections for tightness and make sure battery isn’t flat.
2 could be the starter motor has jammed if the car is manual gearbox put car into 1st or 2nd gear and with the ignition off rock the car forwards and backwards if you hear a clunk noise the starter motor has released itself and should start.
3 if above fails it’s likely to be a solenoid problem on the stater motor and will need to be replaced.
Hope this helps you

When rocking the steering there is usually some noise from a steering system that has a few miles on it especially from the majority of power steering types as not only is the rack slipper bearing likely to make noise but also the hydraulic spool valve and possibly even the rack end bush.
Sometimes the clunking noises can be worrying they are so loud.

If there are steering stops on the lower arms and hubs the noise can be very loud on full lock and a moving vehicle.

There might be track rod problems but there is no point guessing - the car has to be inspected, jacked up and the wheels shook to check for wear and free play and on the ground the steering wheel has to rocked while the steering gear is inspected.

If inspection finds nothing the noise is clearly caused by "acceptable" wear...

I would start by replacing U-Joints. They are really common issues when it comes to clunking noises. I'd start there.

Sounds like a bad cv joint. Easy way to check is to raise the front of the vehicle so both front tires are off the ground. Use jack stands under the vehicle and block the rear tires. Start the engine and put the tranny in drive. Let the front wheels rotate while the engine is idling and turn the steering wheel slowly in both directions. Listen for the clunking noise. You may have to speed the engine up a little to make it work.

sounds like you have a motor mount broken.

can yo give us some more detail like what does the noise sound like? does it get louder as you rev the engine or does it stay the same? Does it do it all the time? is te motor mounts worn out and make a clunking noise?

Is it a metal shaft? When you put it in drive does it make any noise? Does the speedometer move? Does it make a loud clicking sound when you put it back in Park?

check the suspention coil springs one may be broken

Turn off engine . get the vehicle on level ground. try to move driveshaft back an forth or,by rocking in twist motion,,, try to hear a knock,,,this would indicate a worn universal joint.either front or back, if you are good enough to discern which one is making the klunk, change both to be on the safe side. think they may be about 20 dol apiece.

Hi Ali,

This sounds like one or more of your motor/powerplant mounts is broken. Here is an easy test:

Have someone sit in the driver's sear with engine running and trans. in Park.
You stand in front with the hood open. Have them shift from Park to Reverse, and then Drive and back to Reverse and Park, taking time to stay in each gear and give some throttle while holding the brake pedal tight. This will rock or move the engine a certain amount as they shift through the gears and apply power lightly. It will move alot more violently with broken mounts.

If you have a clunking noise on Reverse shifts, you should be able reproduce this with the hood up and pinpoint the noise and/or sight the faulty motor mount with a friend's help. Good luck, I hope this puts you on the right track to fixing this annoying noise.

Sincerely, Tater Todd
