I recently changed the link kits on my car, and while that solved the "submarine about to collapse under pressure" noise that I was hearing, I now get an intermittent screeching noise, more prominent when I drive in reverse. Seems to go away after a couple of seconds, and doesn't come back until the next time the car is cold. Calipers seemed to be fine when I changed my tires.
Any ideas?

Is that shorthand for kittens linked into a congo line? Seriously, I never heard of them. Are you talking about your tie rods?  |

Google says its something to do with anti-sway bars. As compared to sway bars which are for those of us who drink too much.
Can't figure out why your suspension would make a funny noise when you put the vehicle in reverse, though. Are you running into other cars when you back up, BC?

These babies:  (not the exact model, but they look like that) Attaches to the end of the stabilizer bar. It's a Mazda Protege, 1999, about 120,000kms on it... |

Do you use your emergency brake regularly? You might want to look into servicing those parts. When you back up they are designed to reset themselves and work independeantly from the calipers. If they don't get regular use they can seize up and cause some vibration.
Edit: I reread your post and see that you have this noise when you drive forward also. Maybe look at the bushings on the struts?

What you call a stablizer bar I know as a sway bar. They are very simple systems with the only wearing part being your bushings. If your bushing are old, they may have a slight clunking sound to them, If they are very old or completely missing, you are driving a drum on wheels. Soooo.....do you have the basic necessities of life? Like a crawler, a hydraulic jack and two or four adjustable jacks? If so, you need to do a basic visual inspections of all your rubber bushings. Cracks? Splits? Missing? Dead cats caught in between? Lose parts touching the moving parts? Also make sure that if there are any links (bolts), they have not come loose. OR do they have some kind of joint/link? Joint/links allow motion but they also wear down. BUT...here is a problem. If they are slightly worn, you can't really tell from a visual inspection. Next thing, is a bit harder. Well, a LOT harder. You nee to get underneath the car while the car is sitting on it's suspenion. Which really means you need a pit. Which means you are going down to your local car shop again. Be aware about one thing. If they bring the car up on a hoist, they simply can not sway the car up and down to reproduce the noise. Nor can the drive it a few feet forward and back. So they will begin a "repair by replacement" procedure. This is where the older shops and their built in pits allow for better inspections. And the other major problem is that they wont be able to see if for some reason, something has bent slightly/worn and contacting each other. There is precious little space for components in modern cars so it's not unlikely that their "limit design" have used up some tolerances. Anywho...start with getting the basics of life and getting a bit dirty. You may get lucky and the problem is right in front of you. if not, find a shop with a pit and an honest mechanic. Most likely, it may be a few dollars worth of bushing or bent part. Do you have a schematic of what they replaced? If you can get one from the dealer (parts dept), I can point out which is the most likely cause. Then again, NOTHING beats hands on inspection Now for the fun part.....because all the components of the supsenion are linked, what appears to be a problem in one point may be a problem somewhere else. If could go as far away as your steering column or all the way to your strut bushings..or somewhere in between.. "it sounds like" doesn't mean much and "clunks" are notorious for hiding. Again, hit the pit.....and look poor lest you lose as appendage in repairs. Now that's TWO warm Cokes you owe me! |
