Front strut upper insulator
Hey all, I am trying to collect struts and all the rubber peices I need to replace them. Spring seats and springs I'll re-use.
I think I have allmost everything I need, got struts, KYB strut mounts, lower spring seats front and rear. KYB rear strut mounts have the upper seat and bellows integrated.
Up front, the service manual shows a "upper insulator" which looks like the upper spring insulator combined with the strut bellows in one. The KYB strut mounts don't come with that part, and rockauto doesn't seem to have a part like that?
Do I need to buy that one from Lexus/Toyota? Car is a 2001 ES300.

When I change out the suspension components everything will be ordered regardless of wear just a piece of mind knowing nothing will make any noise down the road after a big job has been completed!... Rememeber, "CHEAP IS EXPENSIVE!"

Notice how on this generic image of this strut bellow as it has no upper mushroom head protecting the shroud around the Coil Spring Seat Insulator however on the O.E.M it takes care of that problem eliminating the dirt from entering anywhere causing potential damage..

Yeah I had seen that aftermarket part, like a standard dust cover and bumpstop, but the Toyota uses that upper spring seat integrated with the boot, so not sure what the aftermarket makers expect one to do.
I won't replace the springs, since they are not sagged. My reasoning is that Toyota has a number of different spring rates and free lengths for different models, while and aftermarket replacement is one rate and height that is "good enough" for the whole range, Camry ES300 whatever. In fact the struts will be like that too, but I am OK with the sportier Tokico blues.

Are you running KYB mounts? I heard that they are noisy, and not very good quality.
Too bad I read that after I busted $100 on a set for my upcoming ES330 suspension change.

BTW I don't know what those parts are 48681A/B, were not on my car stock and did not put them on when I replaced struts. Looks like a sort of sheet metal strenghtener for the strut tower to go with the strut mount. But like I said my car does not have them that I can see an works fine.
Those aftermarket strut parts are your problem. It is a downside of the "quick strut" type all-in-one, all your stock quality stuff, springs/mounts/pads get replaced with low quality crap.

Thanks for the help on that random part. As far as the quick struts, I went with the Monroe brand. They offer a pretty good ride and haven't been fairly quite. I do get some noise but after hearing all the feedback, I'm sure it is the strut mounts annoying me.
The noise isn't too bad right now, more of a nuisance than anything. I have about 250K on my car so I am not sure if it is worth switching out the mounts at this point unless they completely go.
