Question about Jeep Cars & Trucks
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.

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.

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.

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.
