Ok...Old lady here getting really frustrated with my 98 durango 4 wheel drive 318. 258000+ miles
Ive got a rattle that sounds like "bearings in a can" if that makes sense on the drivers side at lower speeds and when I get up to 50/55 mph I dont hear it anymore.
Replaced all ball joints, idler arms, inner and outer tie rid ends, Hub assembly and checked the brakes which are fine. Mechanic said my 4wd doesnt have axles so it cant be them? Help please?

 

Is it absolutely related to road speed only, not motor RPM? Driver side front or rear?

 

Answers to Don's questions would help. Is the rotor dust shield rubbing the rotor?

 

Yes answers will help. Another thing I've experienced, if an adjuster spring breaks in the rear drum, it'll rattle around in there until it's removed from inside the drum and replaced.
