![]() My own view is that there are no ‘real’ or ‘complete’ stories there can only be more-or-less plausible stories - unless one is writing a mathematical treatise, without philosophical undertones.

Usually the best approach is a long visual inspection both under the hood and under the body. Depending on the type of noise which is hard to describe via text, the noise could be different items. I do not see any technical service bulletins for rattling noises. Here is a list of some of the most common things I have found from experience. Radiator / condenser- visual and wiggle test.Įngine accessory brackets- visual and wiggle all brackets I somewhat remember a MAP sensor bracket attached to the right front strut tower.īrake calipers- will not rattle when braking over bumps wiggle test. Struts- usually accompanied by leaking from the shaft seal. Push the boots up and inspect for wetness around the spring area. Strut mounts- loose connection at strut rod to center mount nut, loose connection at strut mount to body outer bolts, or broken rubber in strut mount (almost have take the strut mount out to check this one). Springs- would have to be broken or cracked. Sway bar links- would have to wiggle test while the suspension is on the ground (not extended). ![]() Sway bar to body mounts- visually inspect the two body rubber mounts for cracks or damage.Įngine / trans mounts- Apply brakes and rev the throttle in forward and reverse. The noise would be present or you will see the engine jump up or down.Ĭenter engine support cross member (radiator support to center body)- Check the bolts for torque. Inspect the engine mount that attaches to that support.Įxhaust- rap and shake on the exhaust for noises or play.Ĭontrol arm bushings- visual inspection for cracked bushings or off-centered positioning. These are just a few of the common many items. It could still be something simple like a loose light assembly, loose bumper, or even something under the dash. The best process is to narrow down the area the noise is located and the type of noise (metal on metal, plastic on metal, etc). Plancette covered almost every possibility I could think of (jeez your good), but covering them all can be a slow and frustrating procedure. The best method I've found for tracking things is to have the customer drive while I sit in the passengers seat with a stethescope. Once we've identified the noise in question (people tend to identify creaks, rattles, bumps, scrapes, ect. as all kinds of different things), note the exact type of circumstances under which it occurs (speed, powertrain load, chassis dynamics, road surface, ect.). ![]() Finally, I have the driver, or someone else, repeat the action until I can track it to a particular section of the vehicle (what you hear from the driver's seat is not neccesarily where it's coming from I've found problems from a back seat that I swore were in the front when I was driving). ![]()
