SOURCE: Noise driving over rough road worse after new links,struts,shocks

Do not heat or bend any suspension parts. Big no-no. If it's all touching and out of whack, check for possible bent frame. Body-shop that did the past work might have overlooked the frame being bent. All measurements start with a straight frame.Then go after the individual hitch and sway bar.

If my catalytic converter bad will that make my 2001 chevy impala fishtail


No, a bad cat will make the engine run rough or even stall if broken up inside-then it plugs up the exhaust.
Look for loose or broken suspension links, sway bars, loose strut mounts, or other rear suspension parts. Check the front suspension, too. Suspension parts are what keeps the wheels aligned, and allow for wheel movement, independent of the car frame.

Piece that goes from rear brake drum to frame got bent. what is this part called and what does it do?


There are three, we'll call them bars, that go to the rear spindle on your century. The one that goes forward toward the rear door of the car is called a trailing arm. The other two which goe towards the center of the car are called lateral arms, and there is a front and rear. The rear lateral arm is usually the one that gets bent. These three arms position the lower end of the strut/spindle assembly, and if one or more are bent, your rear wheel alignment will be out of whack, and your car will drive funny and you will wear out your tires.

When i hit a bump, the back end of my 2000 eldorado fishtails. Why?


It's likely caused by a worn out strut or struts in the rear. You hit a bump and the wheel bounces because the strut is not damping properly. This causes an effect sort of like riding on only 3 wheels because the bouncing wheel is not supporting the vehicle steadily while it's hopping.

Poor grip in wet conditions


Fishtailing comes from two things...First, all tires are not equal when on wet roads. There is a distinct difference between brands tires and even different tread patterns within the same manufacturer. To find the best tires for your vehicle, you need to experiment with different brands etc. (also look to see what other people are using and how well their vehicles handle.) Worn tires regardless of make will tend to loose traction as well.
Second, vehicle weight distribution (pertaining to weight actually pressing down on each individual wheel). Adding weight to the vehicle by loading up the back with heavy items sometimes helps but will destroy your rear suspension. I use a "non-traditional" fix for this by adding two 20lb flat lead weights to the rear axle (using two longer "u" bolts, one on each side, to fasten them under the spring, behind the brake assembly) With additional 20lbs at each rear wheel, the weight is not on the suspension but adds 40lbs to the rear axle weight, low, where it enhances traction and changes roll center in a good way You may also benefit by adding heaver sway bars to prevent "wheel lift" during cornering (both front & rear must be matched).
I don't know how aggressively you drive, but if you take it a bit easier on turns this will help as well. Driving in 4wd will obviously wear the 4x4 components faster than not using them, but using anything will eventually wear it out! (your vehicle would last a lot longer if you kept it in the garage and didn't drive it.) Use it when you need it...that's why you bought it! It dosen't rain every day!
Hope this helps you ...

Terrible rear end rattle


It's probably the rear sway bar links. If you can jack your car up and check right behind both rear wheels you will be abale to see the sway bar which is connected to short links about 5in long with ball joints.

If either of them are broken or not connected anymore it can cause some pretty loud noises when you ride on rough roads or hit bumps. They run about $35 per link so it's not a very expensive repair.

Rattle under car going over bumps


Take a close look at your springs. My 99 Audi A4 had a creaking rattle that happened when I went over a speed bump or dip in the road, and it turned out the bottom of each rear spring was broken. I replaced them and the noise went away.

Another possibility would be the sway bar end links. Since the sway bar is worked pretty hard, the bushings in the end links will wear out eventually. This can cause some clanking. Look behind the wheel hubs - you should see a short bar or bracket attached to the hub at one end, and to a bar at the other end. The bar will go forward or back a short way, and then across the bottom of the car to the other wheel hub. That's your sway bar. The bushings in the end links (the short attachment bars that anchor it to the wheel hub) or in the body brackets (some cars bold the center of the sway bar to the body with a bushing in a bracket) could be deteriorated and allowing the bar to bang around on the body.

Finally, take a look at the suspension itself. Do any of the bushings where various parts meet appear to be cracked, leaking fluid, or gone entirely? There should be no gaps between any suspension pieces at the points where they meet. If there are, you're missing some bushings and may well have found the source of your noise.
