question about strut tops
I've done a lot of searching on this topic, but can't find a definitive answer. The question is simple. As a general rule, is it standard practice to replace the strut tops at the same time you replace your shock absorbers? Are strut tops a wear item? Do they wear out at the same rate as the shocks themselves? Has anyone out there replaced their shocks without replacing the strut tops?

When buying L-Tuned shocks and springs (which you can no longer do; nyah nyah), you receive only shocks and springs, so you must reuse the 'strut tops'.
The included instructions direct you to do so.

the only way i can see the strut tops / top hats making clanking sounds is if the bolts on them are loose and freely moving around horizontally, which is very unlikely. how else can they make clanks? unless they weren't properly bolted onto the body, then going up and down bumps will make them hit the chassis.
my car has 126k miles, original tops, original rubber spring bumper, no clanks, and using with bilstein HD shocks.

It looks like there are many schools of thought on replacing the strut tops. Some say always replace them when you replace the shocks. Others say there's no need to. And then some say that you only need to replace the front strut tops because the rear ones experience very little if any wear.
By the way, Chuck, thanks for taking the time to post pix of the service manual. That's really helpful.

Isn't this a solid piece of metal and no moving parts. I haven't taken one of these apart and can't imagine they could be worn. Now the spring bumper looks to be made of plasic/rubber so I can understand that being replaced.
Experts please pipe up and tell me I am wrong.

the cushions and spring bumpers are rubber. that is what can wear. I wonder if you can get just those parts instead of the whole top assembly?
e-I also happen to have my stock shock assemblies out in my garage if you want actual pics let me know.
btw-I believe the non reusable part is just the top nut e.

I'm guessing not, and you have to buy the whole subassembly, but maybe. I don't mind spending $64 for each front subassembly, but the rears are $100 a piece, and for something that's not supposed to wear that much, that seems pretty excessive, don't you think?
