2008 elantra suspension clunks in the rear - 2008 Hyundai Elantra

The clunking noise you're hearing from the rear of your 2006 Mazda 6 after installing new shocks could be caused by a few different issues. Here are a few possibilities:

1. Loose or worn suspension components: If any of the suspension components are loose or worn, they can make a clunking noise when the vehicle moves over bumps or uneven surfaces.
2. Misaligned or damaged control arm bushings: The control arm bushings can become misaligned or damaged, which can cause a clunking noise when the vehicle is driven.
3. Worn sway bar links: The sway bar links connect the sway bar to the suspension and if they are worn, they can cause a clunking noise when the vehicle is driven.
4. Improper installation of the new shocks: The clunking noise may be caused by improper installation of the new shocks, such as not tightening the bolts properly.

It's best to have a professional mechanic take a look and diagnose the issue. They will be able to identify the specific cause of the noise and make the necessary repairs.

this indicates a loose / worn suspension bush/s that is allowing a movement of the suspension components on braking or a reaction to braking
I suggest that you find an accredited suspension shop and have it checked out.

rear brakes are sticking get it serviced

indicates failing suspension mounts or diff suspension mounts

check that the exhaust system is fitted correctly and all the rubber straps are in good condition. Check for loose shock absorber mounting rubbers. Have the rear suspension checked out for broken/ failed suspension point rubbers.

clunk noise when coming to a stop could be driveshaft slip yoke binding.clean lubricate driveshaft slip yoke or slip yoke bearings could be worn.

Sorry dude, it is hard enough trying to keep up with all of the clunks and bumps and squeaks and rattles that occur on vehicles with factory suspension parts. When modifications are made...it is anybody's guess.

All I can tell you is to diagnose the problem the way any auto technician would diagnose any other suspension noise...get it on a lift and perform a thorough inspection and/or have someone bounce the car up and down while you stick your head under it and see if you can tell where the noise is coming from.

did they repalce the upper mounts? sound like that's the problem.

the old elantras and accents have problems with the struts siezing up; especially if the vehicle has been lifted/jacked recently.

i see at least a few elantras/accents at the shop every week with locked up struts, its very very common. i am a hyundai tech, so trust me i see this a lot.
to replace the struts you will need a spring compressor and common hand tools.

check the front struts as well, they all tend to go around the same time, push down on one corner of the car at a time, if the car does not come back up after you release pressure, the strut has siezed/locked up.

DO NOT attempt to replace the struts if you dont have a spring compressor...that spring can really mess your day up if you dont properly compress it before removing that top nut.

HI, this noise can be caused by worn shocks,even if the bushings look good, you can remove one of them and check if is hard to constracts ,if not they must be replaced,
