When i drive over bumps i heard a sort of rattling noise from underneath. almost like the shocks are loose or bad. its not really loud is just noticeable and you can feel it a little. could this be the shocks getting bad? 99 jeep grand cherokee limited

Only you can take a look underneath. I can't see it from here.

Noise from the front drive axle can mean many things, so I'm going to describe and give you some ideas based on the types of noises that can come from that area. 1. (WORN CV AXLES) Most common in front wheel drive cars. This is typically is a rumbling or ticking noise heard while turning the steering wheel. It should be addressed immediataly to prevent a loss of steering. If you suspect this a is problem it can be easiliy checked by a mechanic. Someone you know who can safely get under the front of the car and check each axle for broken grease boots and shake/twist the axle checking for a loose joint (but that will not guarantee there is not a problem - this should be done by an experienced mechanic). 2. (BAD BRAKES) Less likely is a brake problem. Brakes would be a loud rubbing noise, but more so when appying the brakes. 3. Lastly, if it sounds like a rattling when you go over bumps or any slight divits in the road, it is possible you may have a broken shock absorber. Best of luck with your car repair!

Exhaust system loose

The most likely reason would be loose or broken exhaust mountings.

This question you resurrected is from 2014!

check the stabilizer links,usually they go bad and make that noise,they are connected to a stabilizer bar

The rattle is caused because the rpm is lower. When stopped in drive with one foot on the brake, press the throttle down slowly until the vibration stops and the noise goes away. Cause? Weak or bad motor mounts, loose bolts or parts.

Check your exhaust and rear suspension for something loose or broken. Problem could be the exhaust, a hanger or cracked pipe. In the suspension it could be shocks, worn bushings, track arms etc. When a problem like this happens you have to get under the car and grab and try to move things checking for loosness. In general try to see what is loose enough that a bump causes it to rattle or bang. Other than inspecting the rear area there is no short cut that can be taken to solve the problem. You don't want to just start replacing parts hoping to fix the problem, that can be expxnsive and unnecessary. Good Luck!!!

If it's making a clunk noise when hitting bumps, check the mounting plates and bushings that hold the rear end to the frame. GM made these plates out of aluminum and the bolts that go through the plate and the bushings rot out and the rear end slams against the frame.

Does your vehicle have hub caps if so check to see whether all the clips are ok.
push up and down on each corner and to see if you can hear the noise, it could be a number of problems, ie shocks, bushes, wheel bearings or the bump stops in the shocks.
also jack the car up and check the steering components by wiggiling the wheel left to right looking for excess play and check the CV shafts and boots, usually if the boots are damaged the CVs will either need re greesing or replacing.
