Recommended parts to go with suspension replacement
#1
I've seen some people give an extensive list of parts that they have replaced when installing new struts and springs. But I've also heard that a good many won't need replacing. Is there a defacto standard of the parts that should be replaced? Also, are there suspension related parts that are a good idea to get while doing this based on 100k mileage?
1) Dust boots - these are usually cracked to hell by the time 100k rolls around, or near ready to crumble. A definite.
2) Strut mounts - based on wear. How do you tell?
3) CV joints - these are usually worn well enough by 100k to warrant replacing?
Please add to this as you see fit... thanks!

It all depends on age and miles.
The basics should be:
1) Dust covers
2) Spring isolator sleves
3) Spring perch mount isolators (upper perch front & rear)
4) Rubber bushings (rears)
5) Front sway bar end link bushings
Thats a nice suspension tune up! Makes the car much quieter.
As far as the strut mounts go, I don't think there's to much to ware on them. Just check to make sure the bushing aren't cracked. A quick test would be to push down on the car and watch the piston shaft from the top, it shouldn't move. If it travels up and down a bit, then the strut mounts may need replacing.

Are the perch mount isolators the same as the "urethane isolators"? And what of the isolator sleeves? Also, are the front sway bar end link bushings different from the front controller arm bushings? I just want to be armed with the right info so I don't get raped by the mechanics (they have a tendency to replace a lot of unnecessary parts around here, CT).
Thanks a lot for your advice...

I wouldn't say the front sway bar endlink bushings are necessary as mine still looked ok, but the energy suspension polyurethane bushings are nice. The endlink bushings can be done without taking apart the suspension, but they are very easy to get to while doing the job. The front control arm bushings are very hard to get off so I don't plan on doing them. As far as replacement parts I listen to njmax as he is very knowledgable on the subject.
I didn't replace the urethane wrap because mine isn't very old, and after doing the job it really doesn't fit incredibly well since aftermarket springs tend to be thicker than stock. I would reccomend the rear isolator bushing (it is rubber) and OEM front strut bearings. I replaced some of my washers and such, but if it's metal it's probably ok. Rubber parts are pretty cheap and easy to replace.
I replaced my front strut mounts with the KYBs since I got a discount from Cattman and they are supposed to be a harder rubber than stock. Be sure to wrap the springs well so you don't get noise. I'm still trying to figure out what my noise is

Hey Hype,
Thanks for going to all the trouble -- that diagram is fantastic. I have a really good idea of how everything fits together now.
I think you're right--all rubber should be replaced. I'm going to make a list of all that because it isn't always clear( e.g. a bushing can be either). I'll also conduct my own inspection and use this to judge the estimates I get.
Any idea of the average cost for spring and strut replacement? One shop that gave me my first estimate was outrageous ($450).

Here's a very useful njmax tip: when the front shocks are being put back together push the bottom in towards the center of the car to get the camber right. Our camber isn't specified as adjustable from the factory and the only way to do it is to push the shock in when you tighten the bolts. After I got my alignment both sides in the front had -.9 degress of camber which is in spec. I was really happy I got my camber even on both sides

When I ordered my struts the KYB mounts seemed like a good idea because they come with bearings but I think that was a mistake. The mounts seem to transmit more noise than the originals did and the bearings STILL make noise even after driving with them for about six weeks. I thought they would break in but nope. I have decided to take them apart and replace them with new OE parts.
SuDZ, There was a big drop in road noise after installing all this stuff but the FEEL came from everything else. I completely rebuilt the suspension with H&R's, AGX's, an AddcoRSB, a Courtesy FSTB, and new front end link bushings at the the same time. Overall the suspension is quieter than it was. I expect it to get quieter still when I put new OE mounts in.
Good luck...

I used the KYB mounts, bearings, AGXs, and dust boots so you would think everything would be cool I considered buying an OEM bearing, but when I replaced my clutch I used the throwout bearing they included and it was fine. You do have to wonder about the quality of some aftermarket parts though. At least the shocks are really good.

I used the same thought process with the mounts but I'm not sure harder is better. I believe any advantage would be minimal because of the small amount of rubber in the mount. Then there is the noise.
My origials were shot so it saved me a step to order them with the struts, so I thought, but now it seems I have a lot of work ahead of me to replace them again.

Thanks for the info and experience sharing, exhip95.
For anyone who has been reading this thread, I stumbled upon this one which also has some great info (especially regarding the spring wraps to reduce noise):
http://forums.maxima.org/showthread....threadid=72678
As to which parts aside from the primaries should be replaced, it seems to be a case-by-case basis. But it does seem the general consensus is that rubber deteriorates over time and that any car with 100k miles or so should definitely have all rubber parts replaced.

Do I really need "(6)54034-85e10-front urethane isolator ("SEAL-RUB" on invoice)-$7.99ea."....Six of them? or is that a typo? Thanks for the help

With only 53,000 miles your isolators are probably still in good shape so you may not need them but they are relatively cheap. They are $6.55 each from nissanparts.cc. If I were you I would order them just to have them on hand in case you did need them.
One other thing. I can remember reading a couple of posts that talked about the KYB boots not fitting very well. If your originals are not torn I would probably just clean them up, treat them with a rubber protectant (brake fluid works great) and reinstall them. The KYB struts are IMHO the best but the other things they make are questionable. I learned the hard way with the strut mounts and bearings. So did Hype.

If I buy all the below and the Energy Suspension parts from Courtesey, will any parts overlap? What parts don't I need from below if I plan on buying Energy Suspension components? Thanks, JsL

i've talked to some people who didn't replace anything other than the dust boots and spring isolators..
and they have no problems... they said the rest of the suspension components were fine even with 100k miles and change.. and that they barely wear, if at all..
i do not mind paying to replace this stuff but is it really that necessary?
some of these things are made out of metal and hard rubber which really can't wear.. especially being sealed up so tight in there..
