Once again you prove to be the sweetest, politest member on HA, congratulations!



For kicks I dusted off hyundaitechinfo's electronic copy of my owner's manual. You know what the manufacturer of the car recommended for a shock replacement interval? There isn't one. The inspection schedule doesn't mention it either. Shocks wear out at different rates for different drivers and driving conditions. They (ideally) should be replaced when they are obviously worn out. The easiest test is to put your weight over a corner of the car (lean on the bumper/quarter panel) and compress the suspension, then remove your weight suddenly. Fresh shocks will rebound to the natural rest position and no farther. Worn shocks will rebound a little higher but stop before bouncing twice. If your car goes boioioioioing, your shocks are worn out and should be replaced.



"We do the things that are important to us." I do regular maintenance and inspections on the drivetrain and brakes. The body is for sh#t, and the struts are worn out. If it bothers you, feel free to buy me a new set and then buy me a spare afternoon to replace them.



The links: good job finding one ambiguous, two from people who sell shocks, and one that says we're both right.



. . . aaaaand once again you two are being jerks to other members, and another thread is spinning off into a ditch. Good job, keep it up.

 

Yup posting nothing but links to websites with nothing but the general consensus and some opinions from industry professionals of when to replace shocks makes me such a jerk



I guess you shouldn't listen to oil companies that say replace oil every 3k miles either huh since they are out to sell oil, replacing timing belts at 60k so the parts department can sell belts



Diaf loser

 

Timing belts have an interval dictated by hard reality. So does engine oil, but almost nobody runs a used oil analysis to determine when they should change their oil. The days of 3,000 mile OCIs and engines that are totally worn out at 100,000 miles are over. Even a local oil-selling parts house came out and said 3k mile oil change intervals for modern cars is excessive.



And this thread is about spring pads, not oil or timing belts, but thanks for participating.

 

weird, in one thread hes the nicest, and in another thread hes looking to say some dumb sh*t to set someone off...







that wasnt very nice...















so anyway, stocker is right... there is no definitive set of miles or hours of use for a strut. you have to actually test it. and you pretty much nailed it too, if you push down on the car, and it bounces more than twice, even the littlest most unsubstantial bounce on the 3rd rebound.... its time to change the absorbers.



and you could do the same with your engine oil, extract one ounce from your engine, and send it over to blackwater oil labs, and they will tell you how much viscosity the oil has left, along with many other facts about your engine. but this is not as easy as pushing down on the hood of your car, so no one ever does it. oil can go for a very long time, if you never rev it over 2500 rpm...lol and live in a cooler climate.

nice.... could this be used as a rear bushing for the lower front control arms if i was able to find the right diameter ?? i might measure the front lower rear bushing cuz the YAYA kit that i just bought from kpec didnt come with them. kspec said yaya doesnt make a bushing for that spot.

 

I don't know. UHMW is one of the materials used in joint replacement implants, it might be suitable. Does anyone make a part that thick of that material for suspension bushings? If I didn't need the car up every day for commuting and could take it apart to check on wear, I might try it.

 

yea, im just afraid it would crack and disintegrate, it needs to be rubbery more than hard plastic, and yea kspec used to sell inserts only for the lower engine mounts, i had to press them in myself, now they sell them with the actual mount. so im sure i could find a 2-3 inch diameter of this stuff....

 

UHMV may not last very long in that space. That with implants is a flawed analogy as all involved parts are polished and very hard alloys or ceramics with a limited range of motion. Actually these UHMW cups are the only replacement part in hip prosthetics :biggrin: I called H&R about their cup-kit suspension and whether it would be beneficial to spend more money by changing these "bushings" to a harder material and build a custom suspension, but they said that the car is a lot less comfortable after that for general road use and a lot more vibration is transferred to the car i.e. rattle. Harder would mean an all metal strut mounting. This is different from stiffening struts etc in the way it effects your ride.

But back to the problem: I had some knocking issues on my car. Apparently these rubber things are of standard size and you can just replace them with same size rubbers from other cars. My tuning buddy - if that is the appropriate word for it - just uses whichever bushing fits no matter the car. Hope this helps a bit. Good luck
