Jeep shocks are pretty much gone by the time they hit 65K. When i had mine changed at 65K, they would compress... and never come rebound. This is on the non upcountry suspension Grand Cherokees.

I second the KYB shocks. My Jeep handles the roads very well and has proven themselves with emergancy lane changes a few times.

I agree on most vehicles but it depends if the vehicle is equipped with gas or oil filled shocks. Oil filled shocks usually last around 40-50K and can leak if one really bad pot hole get to them. Most vehicles are now being equipped with gas filled shocks because of durability and ride comfort.

For the record, it turns out on that car where I thought the shocks were shot, there was NOTHING WRONG with them. I test drove a same year Taurus as the Sable I was looking at, and *ALL* Taurus/Sable twins from that year just have relatively harsh rides by my standards.

The Toyota TRD package has the upgraded shocks and struts. But, I plan to change the entire suspension to Old Man Emu by 60K miles.

Every automobile is different. There are some awesome aftermarket suspension systems available.

I can tell when a vehicle needs new struts or shocks just by driving over a speedbump in it...

I replaced the shocks and struts on my 1988 Mustang 5.0 at 159,000 miles with Tokico blues.

The OE struts were very easy to compress (50 pounds of force is supposed to be what is required) and extended back slowly while making a sick-sounding moaning noise. One of them had also started to rust.

The Ford OE struts on the Mustang were actually made by Tokico, but to Ford's specs, making them different than Tokico-branded struts.

By the way, as a bit of history from this great book entitled "Mustang 5.0 Technical Reference and Performance Handbook":

"For 1984 1/2, low pressure, gas-charged(nitrogen over oil) strut cartridges were put into Mustang service. Ford's 1982 Lincoln Continental was the first domestic production passenger car model to use nitrogen-gas-filled shocks and MacPherson struts. In Lincoln-Mercury Capri applications, this arrangement was referred to as the Nitra-Cushion suspension."

Same book also says that the Mustang got gas-charged shocks (in addition to struts) in 1984 1/2.

So.....how long do gas charged struts and shocks last? Less than 17 years and 159,000 miles.

I hope that's helpful [Big Grin]

On my 97 T-bird sport(which weighs about 3990 lbs), I still have the oem Motorcraft/Ford "sport" shocks (coil-over shocks, NOT struts), and they have 105k miles on them. The ride still feels fine, and I still haven't "felt" any need to change them. Those sports shocks are stiffer than the regular T-Bird shocks, so the car rides pretty stiff anyway.

I also have no idea when They "should" be changed...From what I've heard the oem T-bird shocks are very durable.

I've only replaced one set up OEM struts and shocks in 130k/11 years on one vehicle.
Same here.

So what kind of life can you expect from the typical aftermarket strut, such as the KYB GR2?
They should last as long, if not longer than the OEM shock. If it's the case of them being installed on a domestic car, they should last around 100k with average use.

Also shocks/struts wear out very slow. So its not like they work one day and don;t the next, it is a slow wear item.
Yep and when you replace them, you should notice a big difference in the way the car rides and handles.

They won't last too long if you tow a trailer or have two kids that are always in the back. Every once in a while I'll see a Rav4 go by with two people in the back and the wheels are at an awful angle. Rear shocks/springs just can't handle passengers in my experience.

you think the rear suspension on a Rav4 is bad, take a look at any late model Nissan Altima, or the new nissan Quest. There is an extreme camber change with any weight in the rear.

This design, esp on a minivan (Quest), is poor in my opinion, because more negative camber means less tire contacting the road when going in a realatively straight line, and when you have the rear loaded with passangers, the last thing you need is less traction.
