Question Replacing the struts & strut mounts

I have a 2004 Alero with the 3400 SFI engine and it has about 62K miles racked up on it. There has been a loud crunching noise coming from the front end when I go over speed bumps for some time now that is especially pronounced when it is cold. After reading other threads I am pretty sure at least one strut bearing plate needs to be replaced. I figured while I'm at it I might as well replace all bearing plates/struts. This is something I am planning on doing myself and was hoping for a little help from you guys to make sure I am getting the right parts. So, I'm just going to link to the product pages from napa and if you could alert me if I am looking at a wrong part I would appreciate it. (note: in order to view the product pages, I think you may have to enter your zip code or a zip code that has a nearby napa)

1) Strut Bearing Plate w/ Bearing - Front: http://www.napaonline.com/Search/Det...69_0234776765#

2) Strut Bearing Plate w/o Bearing - Rear: http://www.napaonline.com/Search/Det...052018+102004#

3) Strut Spring Seat - Front Susp: http://www.napaonline.com/Search/Det...524_0258096053

4) Strut Spring Seat - Rear Susp: http://www.napaonline.com/Search/Det...2052018+102004

5) Strut - NAPA Response - Front: http://www.napaonline.com/Search/Det...2052018+102004

6) Strut - NAPA Response - Rear: http://www.napaonline.com/Search/Det...2052018+102004

I listed spring seats above. Are these necessary to replace? Also, if you could give me an indication on the quality of the above parts, that would be great. i.e. how to they compare to the factory originals?

Thanks for the help.

No, only if they are damaged like torn or you see visible signs of wear. I don't use NAPA parts just the GM/AC Delco brand only so I can't comment on how those parts will work.

Re: Replacing the struts & strut mounts

Thanks for the response. Now, I have another question regarding alignment. I understand that when I replace the struts, strut mounts, etc. I will need to have the car aligned. However, I am thinking I may just do the front end for now and then the rear later on down the road. Is there any reason why I would need to get the rear wheels aligned or would it be sufficient to only get the fronts done?

Re: Replacing the struts & strut mounts

Nothing wrong with doing just the front struts and rear later. The rear struts last longer than the front. Alignment would depend on the shop doing the work. Some do all 4 only and some will do just the front end alignment at a reduced charge. Good luck!

Re: Replacing the struts & strut mounts

not sure if its too late, but one thing you might look into is what they call a quick strut assembly, these are completely assembled struts, to where all you have to do is take out the old ones and put these in. not all parts stores carry them, and yes they are a little more pricey, but you get a new spring, strut, strut mount and bushing, versus replaced the strut and mount and bushing. just a little extra security in my opinion. When you go to do your alignment, ask the shop about the alignment machine, age is the one thing you wanna kinda watch for, and brand. Some top quality machines are hunter, john beam, and few others. Reason i say age is that john beam has machines that are over 10 years old im sure, you want a newer machine cause that just means it has been taken care of better, and all the updates should be applied. hope this helps.

Angry Re: Replacing the struts & strut mounts

Well, I got the new struts, strut mounts, and coil spring seats installed pretty easily and I thought the front end noise would be long gone. However, I was driving my car this evening and the noise was still there, although it seemed like it was reduced some. I only hear the noise in cold weather and when I am going over speed bumps. Any ideas what could be causing it?

Re: Replacing the struts & strut mounts

I just wanted to provide a last update to this thread in case someone else out there was having the same problems as myself. This weekend I finally got around to replacing the front stabilizer bar bushings and links and this seems to have completely eliminated all of the noise coming from the front end. Thanks for all of the help.

I haven't come across any posts on this forum detailing how to do it. I have a Haynes manual and that does a pretty decent job explaining the procedure. A better option would be a factory service manual. For some cars you can find them online for free, but I haven't been able to for the Alero yet. I should probably just break down a buy one, but they're pretty pricey and I'm a poor college student.

The Haynes manual should be pretty easy to locate online and the factory service manual can be found on the GM Goodwrench website for $135.
