Question about 1994 Jeep Cherokee

1 Answer

Running loud and thumping on floorboards

For a few days now there has been a loud-ish running noise that gets louder the faster I go. Additionally, every time I hit a bump something springs up against the floorboards and bumps my foot. The guys at the shop informed me that the clips holding on my catalytic converter are shot and I need to replace it ASAP. The catch is (they claim) that it's a special piece with the tail pipe and the muffler and I can't replace one without replacing all three. I realize this is an older vehicle and can accept certain things will rust etc, but don't want to waste my money if they are working me over. The shop doesn't exactly seem to be 'woman friendly'.

Your cat is on the passenger side of the vehicle,,, don't see how it's hitting the floor under your foot. Get another opinion. Could be a transmission mount or some other part that's bad, (even an exhaust pipe hanger, but those things would be transmitting thump, and would not be under your feet.If the shield on the cat is loose, I've used green wire ground clips made for grounding electrical junction boxes on home wiring systems (available at any home-depot in the electrical department for about $2.00 for a bag of about 15 clips) to re-attach the shield so it dosen't vibrate. It is not heavy enough to cause a thump though! Have someone else look at it!!!

Loud rear whine, not brakes new ones fitted


Was noise there prior to brake replacement? If so, possible wheel bearing noise. Noise should get louder the faster the wheel rotates with a bearing problem.

something is rubbing underneath by tires or maybe a bad axle or ball joint or wheel bearing,could even be a stuck caliper,you will have to look at your tires on backside to check your ball joints,

Front end thumping that gets faster with speed


check for bulges in the side walls of the tyres and check for belt separation. Disconnect the front axles into free wheel mode and if the noise is not there it will be tyre related as there is no movement in the diff or drive axles

Thumping noise coming from front end


If the noise indeed does get louder when turning right, I would suspect the leftside hub.

There is no way to estimate cost until you know the exact case of the noise. See the dealer for a test drive so a tech can listen to it.

Everytime i turn the steering wheel i hear a loud clunking noise, i know its not the strut mounts, i know both tie rod ends are brand new within the past year plus they dont make a clunking noise like...


clunking noise may be bad steering rack. either the bolts that hold it to the frame may have worked loose,the center of your vehicle is where the steering racks located,just under the center of floorboard.under dash but on floorboard.make sense? try turning the steering wheel with engine running,place your hand under the radio,but on floorboard,when you turn the steering wheel from side to side,do you feel a thump? if so,then your steering racks loose or bad. the only way to know for sure is to have someone who knows about the steering rack to inspect it visually. thank you for choosing fixya.com

Sounds like the starter need to be replace or rebuilt.
The clicking is due to the starter still partially engaged. Grooves are worn on the contactors and the plunger is sticking in the starter.
