    Re: Yet another Strut question...

    Hi guys, the struts do make your wallet scream at the sound of the replacement parts... my 97 ETC bounces like a hooptie (or worse) at certain speeds over bumps and I have determined that they definately need replacement; however the local Advance auto parts store here has aftermartket replacements for just under $500 a piece (still hurts but not as painful as $800 from the stealership), so far seems to be the best choice of replacing the struts as I really don't want to install the passive struts.

    But back to your question 300HP ETC, my opinion based on the available info is if your ride is decent particularly over bumps it could be bushings or the stabilizer link as mentioned above. Good Luck!

    Re: Yet another Strut question...

    Dude, NoFear365@yahoo.com, it sounds to me like you need new sway bar end links. They cost about $60 for each end but they are usually the cause of the clunk sound in the front (if its not the struts, and from what you said yours is not the struts). I just replaced mine, its not that hard to do.

    This condition may be due to the stabilizer bar rubber insulator "walking out" of it's seated position between the engine frame and the stabilizer mounting bracket/clamp during large suspension movements.

    Correction

    Install a 50 mm (2 in) by 38 mm (1.5 in) strip of anti-slip/friction material such as 3M® SAFETY-WALK ™General Purpose Tread Tape, P/N 19221, or equivalent, between the engine frame and the stabilizer shaft insulator.

    4. Remove the stabilizer shaft insulator (3).
    5. Clean the engine frame surface (5) of any debris or grease.

      • The adhesive side is installed on the engine frame.
      • The 50 mm (2 in) side of the strip must be positioned fore/aft on the engine frame.
    7. Install the tape to the engine frame (5).
    8. Install the stabilizer shaft insulator (3).
    9. Install the stabilizer shaft bracket/clamp (2).

    Re: Yet another Strut question...

    Hi, I hope y'all get your front end rattles fixed;
    but ....... what's this thing that lots of you seem to have about buying parts at rockauto dot com???? they are SO expensive, literally every single time I check & compare prices with gmpartsdirect.com
    Struts (GM OEM) for example for my '99 SLS are $555 at rockauto, but $387 at gmpartsdirect (these are the eight hundred dollar ones from the dealer). just priced them a couple of days ago, because I too was told I need new struts.

    and listen, I have no affiliation with either of these discount suppliers of GM Delco parts.
    so check it out.

    Re: Yet another Strut question...

    Occasionally I've found rockauto to be cheaper than GM parts direct. GMPD tends to charge a hell of a lot for shipping.

    Anyway I've never worried about my car, it makes a clunking noise when it goes over bumps, but it still rides great (not so much now that I have 40 series tires on 17s) and handles great (even better now...) so I haven't worried about it. Thing is, I can't even tell if it's coming from the front or the back, how the heck do you tell with a noise like that? Stick your head out the window?

    I AGREE with you, GM parts direct has great prices, I use them alot.

    I am disappionted because I checked my front swaybar bushings today and did not find anything wrong as described in the above post, I was hoping to find the source of my front end rattle there, so I may be going with new struts as well

    Did you check your end links? Remember BOTH wheels have to be level with eachother in order for the bar to not be under load. Whaen it is under load, it is very difficult to find any problems with the end links.

    Re: Yet another Strut question...

    LOL I posted this originally, and I am starting to hear the clunk/rattle when going over speed bumps (as I'm coming out of them).

    Anyone try it? Krashed989 ... where's a good place to go, or what's your advice? You seem to know a lot about alignments/suspensions. Your advice is appreciated.

    Re: Yet another Strut question...

    If the clunk happens when you're coming out of a speed bump than it is the rear that is making the noise. There is a sway bar back there too ya know. If the noise is coming from the rear, 90% of the time it will be from the rear sway bar bushings. The other 10% is for those rarities that you have to search for. My favorite way of searching for the cause of clunks is with a rubber malet. You have to know what you're hitting though, otherwise you may break something. Just give the sway bar a good whack in various places and you should be able to pinpoint the culprit. Remember that the wheels have to be level with eachother though.

    Re: Yet another Strut question...

    Has anyone tried this yet? I think after the holidays, I'm going to have this done. It's just getting worse and worse. I feel it in my floor board and steering wheel. It drives me nuts! Its definatly a bushing issue because when it rains or when I get the car washed, the noise goes away 100%. Also, the car handles 10 times better as well. If I'm going straight, it rattles like CRAZY! If I make a turn, the rattles go away until I straighten the wheel out.

    And yes, I've changed the stabilizer bar links. They are OEM Delcos and are less than 7 months old now. They've only got about 3000 miles on them. (I only drive about 6000 miles a year now)

    Re: Yet another Strut question...

    So the holidays came and went and I finally brought it into the shop. The mechanic now says that he feels it's the strut mount. I told him that I already had them changed at Cadillac. He said that with the car up on the lift, he can replicate the noise by having someone turn the wheel back and forth. He said that when the wheels turn left and right, he can actually see the strut moving. Nothing is loose on top of the tower as well. He said it's either the mount (I doubt it because this didn't fix it originally) or it's the physical integrity of the strut itself...

    I'm ready to give up here... I'm ready to just buy the $500 package from Strutmasters and start over again...

    Re: Yet another Strut question...

    NoFear,

    I think my symptoms are similar to yours. car squeaks when it bounces up and down over bumps in COLD weather. In warm weather it's barely noticeable, if i remember correctly.

    I had sway bar bushings replaed last fall, and that eliminated a lot of rattling over bumps but there is still some there.

    I took it in to a shop to have it inspected and they said it needs new struts all the way around, but the fronts are far worse than the rears. I dont think the rears are that bad at all.

    I have ordered new front struts, OEM, the $800 a piece ones. As soon as they come in and I get them on the car I will post back with the results. I will also make a document on how to replace the struts like I did with the rear brake pads and rotors.
