Shock and Strut Replacement -- Cheap, OEM, or Upgrade?

158 messages,  Last post on Nov 04, 2009 at 7:41 AM

You are in the Maintenance & Repair Forum. Your Host is mr_shiftright

What is this discussion about? Performance Mods, Suspension

This forum is to discuss shock/strut problems and how to best deal with what is becoming a rather expensive replacement item on cars approaching 60K-80K miles. Are products sold by chain stores just too cheesy to give decent performance? Is it worth upgrading shocks and struts if you are a more or less docile driver? Is OEM a rip-off for what you get?
 
Let's hear your ideas and experiences.

I am not familiar with your Celica, but I'm going to assume that the mounting for most strut/shock assemblies are similar.
 
Your top mounting plate bolts to the body,right? The one's I've seen have a heavy, stiff rubber insert/grommet/bushing with a hole through the center. The hole is where the threaded end of the shock goes, right? That hole usually has a metal sleeve (bushing) in it that prevents the shock rod(terminolgy?) from rubbing directly against and wearing the rubber. It sounds like the cylindrical metal piece you are describing is that bushing. It's part of the mounting plate, and probably not supplied with the shock itself.

Thank you, yes, you and I are talking about the same basic part. This is about the rear struts. No bushing came with the mounting plate (bearing).
 
In my Celica, the old struts only had a metal sleeve (bushing, there was NO rubber), through which the shock piston (rod) was inserted, i.e., the threaded end was inserted. I re-used that part because a new bushing did not come with the new "strut." There were no instructions in the Celica repair manual (Haynes) or with the new strut talking about this part, so I wasn't sure it was needed or not, and if it was needed, I wasn't sure whether it should go onto the shock rod prior to or after the mounting plate (I forgot to take a photo of the "before" condition of the old struts). My decision was to go ahead and use the old bushing, and to put the mounting plate on the rod before the bushing, just before the damper nut.
 
I am seeking verification that what I did was proper or not. A shop did an alignment yesterday, and did not complain that it couldn't be aligned, so I assume it might be ok, but still want to understand what is actually right, and learn what that bushing is for, so I could understand what would happen if the bushing had not been used.
 
BTW: the strut boot (kit) had a plastic "bumper" up top that replaced the one that was on the original strut, but the original one fit completely over the shoulder of the threaded part, onto the slick part of the stainless steel of the piston. This means that the new plastic bumper fits around the shoulder and therefore about 3/32 in of plastic is wedged between the mounting plate and the shoulder of the piston, holding whatever forces get transmitted at that point. That seemed a little strange to me, but all of the clunking from the rear end is now gone.
 
I do appreciate your kind response, many thanks.

1986 Neon with 60000 mile. Same thing just happened last week to my mother-in-law's car. She took in in for a tune-up, got it back with no suspension.
 
I thought she was kidding till I drove it. Absolutely no suspension. It felt like someone had welded the shock absorbers together. The garage said it was not their problem.
 
My question, did you ever get to the bottom of "What happened?" Or, who did what?

OEM VS AFTERMARKET SHOCKS & STRUTS by dexmon

Hi everyone I own a 2005 lexus ls 430 with 256,000 miles and my shocks are leaking. Lexus dealers charge almost a thousand dollars for 4 shocks. Should I buy lexus shocks when I can get KYB shocks for less than $400.00. Does anyone out there can give me some advise on what to do? I don't want to sacrifice ride comfort and also I don't know how long the KYB's will last, please let me know

Well this is kind of an iffy situation. On the one hand, for a car of this type you'd probably want something better than KYB, like Boge or Bilstein, but a) I don't think these two manufacturers make a replacement shock for your car and b) besides, you have 256K on the car already, so a huge investment might not be the best idea.
 
I guess I'd go with KYB, but be prepared to sacrifice some ride comfort and durability I think. Or spring for the OEM if you plan to get another 100K out of the car and it's otherwise in really nice shape.

I own a 98 es300 with 197K on the od, I am not the original owner. At about 160k, I replaced all of the struts with kyb's. I have not had a problem since. I do not understand why everyone thinks that kyb's are cheap. I mean, they appear to be of good quality and they do have a lifetime guarantee. I have not experienced any ride degradation, in fact, the ride is quite good. As for durability, I do not know since I've only had replaced 30K miles ago, but how bad can they be, again, with a lifetime guarantee? I would like to have bilstein struts too, but they do not make them for my car, and are they that much better than the other manufacturers out there?, In addition, they are very expensive. If the bilsteins are so darn good then why don't they make applications for all vehicles? Stick with the kyb's, they are fine.

Kayaba Industries in Japan has made shocks under the KYB name for over 50 years. They manufacture OEM shocks for Lexus, Infiniti, Mazda, Nissan, Subaru, and Suzuki. That being said you might be replacing KYB shocks with a new set of KYB.

A lifetime guarantee really doesn't support the idea that the product is of particularly good quality. Midas mufflers have a similar arrangement, which is really saying "bring in your prematurely worn out old muffler and we'll replace it with another one of equal quality".
 
I think KYB meets the demands of a substantial number of drivers but I think the product has design limitations---and you may indeed never exceed these limitations. Both a $99 and a $1000 digital camera take pretty good pictures, but......

Hmm. If you think products like Bilstein or Edelbrock are superior to KYB, we need to take a look at the company. Kayaba Industries which markets in the US under the name of KYB far exceeds that of either Bilstein or Edelbrock.
Kayaba Industry US
 
Also a look a the types of products that they manufacture.

All I'm saying is that due to their limited marketing efforts, the technology that this company represents is well understated. As an oem manufacturer one can understand their limited marketing efforts to the masses.

Regardless they still build to price like any other corporation. Toyota makes a Yaris and they make a Lexus LS.
