Question about Pontiac Grand Prix

1 Answer

When I turn my wheels to the left and right 45 degrees past center I hear a hard "clunk" noise.

I have double checked to that all the lug nuts and wheel studs are tight as well as the lock nut for the wheel bearing. These are all tight and don't have any sloppiness to them. I believe the left front shock is starting to go bad, but I'm not positive that this is what is causing the clunk when I turn the wheel. The noise is coming from the left front only. I'm looking to rule out as many possibilities before I throw parts at the problem.

If your car has struts, its probably the upper strut mount. Don't rule out a broken spring.

grab a large punch and hammer and knock out the old broken one. Push the new one in and re tighten. This will pull it into place and because it has splines it should not spin while doing so.

SOURCE: tire will not come off when lug nuts r removed on front right whe

A few good cracks with a hammer or mallet will most likely break the wheel free from the lugs.

SOURCE: I have what sounds like

Jack up one side at a time and get a big bar or a strong 2x4, lift the wheel, have somebody lift while you peek at the inside and see if you can see something loose, grab the wheel and shake it left and right, It should tell you something, If, not, try the other side, Something gotta be clinking in there somewhere. You don't need a socket to get the bearing nut off, it is not tight, it is snugged up and then backed off, If it were put on tight, It would overheat in a few miles and smoke you out of the car and weld itself to the spindle/ axle, which ever you have there, most front drive cars don't have front end problems like 2 wheel drive cars, but they do have bearing problems. Hope this helps.

Clunking on left front end

Hey Tony, tighten your lug nuts on the wheel. If it's not that, jack and remove the wheel and check for loose brake caliper. But most likely just loose lug nuts.

Knocking Noise from Front End Toyota Corolla 2004

Ensure the wheel nuts and Axle nuts are properly torqued to the specification. Lift up the front wheels, place supports under the car and do the following:
- Sit if front of right wheel, slightly move it right and left and feel any abnormal noise if coming out of it. If click-click or Tuck-Tuck sound is observed it could be due to the excessive play in the tie rod end, rack end, ball joint wheel bearing or U joint. Next hold the Tire with your one hand at the top and with other hand at the bottom. Shake the Tire inside out and feel any noise or play. If play is observed, it could be the worn out ball joint or the wheel bearing. Now hit the Tire at the top with rubber hammer and observe any rattling noise coming from near the center of the wheel. If you could listen to the extra noise it could be due to the dried up caliper pins. Grease the pins with graphite grease. If all is found fine, similarly check the left wheel and repair as necessary.

Clunking noise comming from front

check your lug nuts first. if there tight jack the front of the car off the ground, then wiggle the tire left to right and up and down. if you have any play then your wheel bearings are out. if you dont have play then reach around to where your front wheel drive axle attaches and wiggle it in the same fassion. you should have your answer when you do this to both sides

Front-end vibration in my lincoln ls v8. you can only hear it when you go over 45 mph

I strongly suggest you check the lug nuts for tightness and if they are ok on your right front tire then go to a tire service center and have them balance and check the belts-either is very dangerous because it will A-fafall off or B-blow at high speed. Good luck!

Knocking on suspension

This problem could be a number of things, the best thing to do is to check the front suspension. first jack up the car , front of car with e- brake on, the first thing is to make sure the wheels are not loose, i have seen loose lug nuts cause this problem, shake wheel and then check lug nuts that hold wheel on.

Grab hold of one wheel and shake it in and out, this is done with hands on the left and right of tire, and then top and bottom of tire, you are looking for play in the steering components ,
Next you will need to check the ball joints, to this you will need a floor jack, place the jack under lower control arm, this will take pressure off the joints by compressing the spring, then with a bar placed under the tire lift bar and have someone watch for movement in the ball joints.this is to be done on both sides.

If there is play an these parts then replacement is needed but keep in mind a little play may not cause the clunk you hear, there would have to be a lot of play. the last thing in the front suspension would be the control arm bushings or sway bar bushings. these you will need to look at closely..

good day

Rear end is shaking

could be as simple as an out of balance wheel/tire, this is the most likely if it's only noticeable above a certain speed, it is worth checking that the lug nuts are tight (70-80 ft/lb for alloy and 100 ft/lb for steel wheels) also, try shaking the wheel side to side (hands on top and push/pull fairly hard) if you can hear any clunking noises or notice movement beyond the little shaking the rest of the car does, there's an issue that it needs to be taken in for and is a safety hazard.

You have one or more loose wheels. You are in danger of loosing the wheel and hurting your truck, yourself and me. Don't drive the thing any further than you have to. What you are hearing is the wheel(s) chucking on the lug nuts. Let it go long enough and it will shear the studs and the wheel will fall off. If all the wheels check O.K. check the drive shaft for a bad universal but I'm convinced it is a wheel. Good Luck.
