Question about Jeep Cars & Trucks

1 Answer

I hav a knocking noise under the hood of my jeep cherokee. I recently had the upper ball joints replaced and the knocking stop for a while and now its back full force. The noise sounds like its coming from the front right of the car. I hear it the most when I am trying to accelerate from a stop. The banging is really loud then, Then I hear it again when I go to stop. As the car is lsowing down, I hear the banging again. Help!

Knocking in the engine varies from simple failure to detonate to you are about to throw a rod. This is something that can be difficult to diagnose and if misdiagnosed, costly to repair. I would take that in to a mechanic as soon as possible. Barring that, I would check all your spark plugs.

SOURCE: knocking noise

Check your tie rods and the drag link bar which controls the steering. Have someone turn the steering wheel back and forth while you are underneath and you should be able to pinpoint the noise location.   I had the same problem on my 2001.  Replaced the lower tie-rod ends and also the ones on both sides of the drag link. This solved the problem.  Whether you do this job yourself or not, you will definately also need an alignment upon completion.

SOURCE: 2003 Protege5 front suspension knocking noise

Yes there is a bearing on the front stuts on the top under the upper strut mount and it is plastic. But the last guy was right it is most likely your struts, or it is your stabilizer links. There doesn't have to be much play in the links to make a tonne of noise. I replaced all my struts myself and it solved the problem for me. You can buy fully assembled strut kits for most veh so you don't have to compress the spring...just dont loosen fully the top middle large bold on top of the strut lol.

SOURCE: Hi My jeep cherokee 2.8 crd has knocking sound

Well, something is broken. I suggest that you get it on a lift, and listen with a Stethoscope and be sure the noise is in the tranny. There is not usually anything good that comes from a noise like you describe. A broken tooth on a gear damages the mating gear and those parts add up fast.

SOURCE: 2002 grand cherokee thumping noise coming from rear susp.

I had a similar problem about a year after having rear shocks replaced, turned out there is a round metal tube through the bushing at the top end of the shocks, if you tighten the mounting bolt down too tight these crack and allow a bit of movement which causes the clunk. Replacing the shocks (at another shop) solved the problem - two years ago, no recurrance. Take out the shocks and check that little metal tube (I'm sure it has a more technical name); if it is cracked, try to find replacements (otherwise you have to replace the entire shock) and be very careful when reinstalling them not to tighten the mounting bolts down too tightly. Don't know if maybe there is a torque specification for these mounts, perhaps a Haynes or Chiltons manual could help here. Good luck.

1998 jeep cherokee sport front end clunk when turning left


This could be almost any front end part, these Cherokees have front end problems that will drive anyone crazy, even techs .
Take a look at front end components, check for any broken sway bar link ends, these sometimes break and make noise when turning or going over a bump, they hit other components due to being broken.
The first thing is to check the front end. there are upper and lower are bushings that wear out, these are tough to check, you will need to really take a good look at them for wear. the next thing is the track bar, this is also hard to check due to the force on it, but you will need to check it by watching it for movement at the joint end as someone jacks truck up and lowers it.These trucks are also famous for ball joint problems, you will need to check them. jack up one side about 4 inches off the ground and with your hands grab the top and bottom of the tire and wiggle tire hard to check for movement in ball joint, if there is play then replace them. upper and lower, if there is no play then slide bar under the tire and pull up and and down this will apply and release pressure , this will allow you to check for play in the ball joint. you will feel and see movement in ball joint, have someone watch the ball joint as you pry on tire.
this is a start, good day.

Replace front ball joints on jeep


Hello there,
To replace the front ball joint on your jeep. You will be needing these instruments, Lug wrench Jack, Jack stands, Wheel chocks, Socket set, Wrench set, Needle-nosed pliers, Hub puller, Ball joint separator, Hammer, Ball joint press, Torque wrench, then, Please follow the steps below:
Loosen the lug nuts on your Cherokee's front tires, using the lug wrench. Jack up the front end of the vehicle and brace it with jack stands. Place wheel chocks behind the rear tires to prevent rolling. Back the lugs off the lug nuts, and remove both front tires from your Cherokee.
Remove the bolts behind the calipers. Lift the calipers off the hubs and set them on a support so they do not stretch the rubber lines.
Pull straight out on the brake rotor to remove it from the wheel studs.
Remove the cotter pin from the end of the axle shaft that extends through the hub. This is best done with a pair of needle-nosed pliers. Remove the drive nut from the axle shaft, and set it off to the side.
Remove the three bolts retaining the hub. These 12-point bolts are on the rear of the assembly.
Separate the hub assembly from the knuckle; a hub puller will make this easier.
Remove the cotter pins from the ball joints, using the needle-nosed pliers. You must detach the pins from both the upper and lower ball joints. Use a socket and ratchet to remove the nuts at the bottom of each ball joint.
Insert a ball joint separator between the knuckle and the ball joint. A hammer can be a big help to drive the separator into place and force the knuckle and ball joint apart.
Use a ball joint press to remove the joints. The ball joint press will force the upper and lower ball joints out. Follow the instructions included with your press.
Insert the new joints, using the ball joint press. You must reverse the motion of the press this time, pressing down on the upper joint and up on the lower joint. Be sure that the joints are completely in place within the knuckle.
Reinstall the steering knuckle onto the new ball joints, and thread the nuts onto the bottom of the joint. Check your manufacturer's specifications for the torque requirements for the nuts. Insert the cotter pins, and bend them down around the nut.
Reassemble the hub and axle around the knuckle. When replacing the three bolts, torque them to your manufacturer's specification.
Place the brake assembly back into position, both rotor and caliper. Replace the two bolts you removed on the caliper. Torque the bolts to your manufacturer's specification. Place the wheel back on the Cherokee, and tighten the lug nuts appropriately. With the wheel secured, lower the vehicle back to the ground.
Hope this was helpful to you. Goodluck Elect_Comp

2001 Jeep grand cherokee motor knock 4.7 motor


First, if the noise is from the upper part of the engine and is more of a tapping than a knock, likely you have a problem in the valvetrain, most often a bad lifter or worn rocker arm. If the noise is low, deep inside, the noise is from a bearing. This is generally accompanied by lower than normal oil pressure. Regardless of the underlying cause, correcting the cause will not stop the knock. To do that correctly, the engine needs to be removed and all crankshaft bearings and the crankshaft itself need to be replaced (crank can sometimes be "undercut" and thicker bearing shells can be used depending upon the amount of wear.) If caught very early, sometimes only one bearing can be replaced in-car, but in 99% of all cases I have ever seen, most will fail again, sometimes more severely if done this way.

2004 jeep grand cherokee. I am doing the rear


first. i don't know why you would have ball joints in the rear end. it is not a steering axle. don't do it. your gona get hurt. take it in and let a machanic work on it. second you don't take the shocks or springs out to replace ball joints. just the wheel assembly comes off. and yes i believe there are alighnment adjustments for the rear. but i wouldn't do that at home myself. take it in.

You should get a new drive shaft or get yours rebuilt. There is a guide socket and ball in between your CV joints. If that wears out you will here a knocking when torque is applied to the drive shaft. Hope this helps!

Replacing a '98 Grand Cherokees ball joints


The only parts you need are the ball joints, upper and lower, a total of 4, if you need all 4. As far as tools, you'll need wrenches, a removal and installer tool, the ball joints are pressed into the control arms, and a ball joint to steering knuckle seperator tool.Without those special tools, you will never get them changed, if you do it yourself.
