Ok, so I'm tired of hearing noises from the front suspension. Everytime I hit a bump it sounds like it pops. I feel like it rides crappier too than it should. It's got new struts, strut mounts, and springs. To make it easier, I'll just put all my questions separated so it's easier to see (I got lots Laughing )
1.) What parts there are in the front suspension that can be replaced?
2.) What are your recommendations on these parts (brand and place to get it from)
3.) Should I go about replacing all the parts or just what you think is causing the noise?

I see that the cv is throwing grease everywhere.
4.) Is it called the cv half shaft assembly, the whole axle?
5.) Do you generally replace both sides?
6.) What is a good brand to get and where do you get it from?

The passenger tie rod end is going bad and I have a replacement to put on for that. Do you think that would be causing the problem?
As far a suspension goes, If I can replace most all of the front components for a couple hundred bucks I probably will, it needs it. It's almost 11 years old Shocked

I can't tell you anything on the axle issue as I haven't dealt with it yet, but popping can indicated cradle bolt issue. I've been dealing with this since I got the car. As well as a noisy ISS.

A popping sound could be the ball joint.

The CV axles I replaced in twos just because I knew they were throwing grease for quite some time. $46 a side from Autozone. Whatever brand they have in stock, it came with a lifetime warranty so you can't beat that!

Could be a broken sway bar link. If the link popped the head of the bolt off and it is still attached on the otherside it will make clunk when going over bumps. Really, you just have to put it up in the air and see what is what. If something is popping it should be fairly oblivious at this point.

-Check that sway bar link did not break, often overlooked because the majority is still attached
-Grab tire at 12 and 6 see if there is play if there is play then it is most likely a ball joint
-Check the springs, I have seen them over looked. Most times if the car is not moving and you turn the wheel you can hear the spring pop

I thought 12 and 6 indicated a bad hub, or is that both?
If an endlink on the sway bar was broken, would it make the car sit kind of crooked? This happened on the Blazer we used to have and it sat way crooked. And my car is an 1/2-1" higher on the driver's side than the passenger front

A bad hub will have play all the way around. Sounds like you can find what you need by just turning the wheels and taking a peek. Let us know what you find.

There is almost no way you can check a balljoint manually without removing it, there is a ton of spring pressure on it at all times.

I have a suspicion that bad hubs lead to CVs throwing grease. Lift up your front end and shake the tire at 6 and 12, if there is any play, you need new hubs! Replacing just the axle will put you in the same situation shortly down the road.

If there is any play at 3 and 9, then check your tie rods, but a bad hub will also have this play.

Have you ever replaced your engine and trans mounts? Mine had collapsed and were allowing the engine to shift around quite a bit causing some nasty noises under braking.

Never replaced anything except the struts springs and mounts. Braking or accelerating doesn't affect it. The more I listen the more it sounds like a rattle than a pop. Like what a strut or body mount sounds like when it goes bad

Have you checked the front control arm bushings? It's a really strange (and in my opinion poorly engineered) design, as it is bolted to the cradle in a vertical position as opposed to the rear control arm bushing which is mounted in the classic horizontal fashion.

In other words, the rear bushing rotates around the mounting bolt as the arm moves up and down (like when you hit a bump) and the front bushing relies only on the flexibility of the rubber mount. Also, the front bushing isn't even solid; it has two slots in it to allow more flex which makes it even weaker.

Common sounds made by a bad front control arm bushing include popping and clunking, kind of "crunching" sounds when you hit a bump, or go from park to drive or reverse. It will also cause the car to tend to under-steer or over-steer, depending on which one (left or right) is bad and which way you are turning the car.

Maybe long and boring, but I hope it helps!
