JUDGE Posted December 27, 2009 Share Posted December 27, 2009 My truck came with Monroe Reflex struts & shocks and I'm wondering what to expect in longevity. They sit at about 40KMs currently. Thanks! Link to comment Share on other sites More sharing options...

MY1PATH Posted December 27, 2009 Share Posted December 27, 2009 a sales man told me If you've had new tires you might wanna consider new shocks. I think he was implying that the life of a shock is compareable to the life of a 50k tire? personally, I just do the bounce test; push down sharply on one corner if it feels like an unchecked spring they are worn out if it "bounces" noticably or cycles 3 or more times they may be worn if it returns to ride height with very little extra motion they are fine Link to comment Share on other sites More sharing options...

Alkorahil Posted December 28, 2009 Share Posted December 28, 2009 (edited) ^ Seconded. I would add, replace all at the same time as well to get more out of them. I hate it when people have all 4 with many many miles on them, or worse yet all 4 worn out and they replace only the front or rear, it just makes the new ones work harder and wear out faster.

westslope Posted January 9, 2010 Share Posted January 9, 2010 All good advice. But as a rule of thumb how long should, let's say, aftermarket shocks on a stock set up last? 100,000 km? 200,000 km? Do years of use matter? In other words, does simply sitting parked also age the shocks? Link to comment Share on other sites More sharing options...
Kingman Posted January 9, 2010 Share Posted January 9, 2010 (edited) It depends on the brand. Some people report Monroe or Rancho shocks going out within 10k miles, while other shocks such as KYB, Fox, or OME can go for 100k+ miles.

adamzan Posted January 10, 2010 Share Posted January 10, 2010 My monroe front shocks lasted 40k kms. I put oem ones from the parts truck that had over 200k kms that work like new... Link to comment Share on other sites More sharing options...
Precise1 Posted January 10, 2010 Share Posted January 10, 2010 I'd say it is more the unit design and driving conditions that have the most impact on shock life. They are not created equally and what lasts in California on a commuter may not last on a wheeler on New York, too many variables... In other words, does simply sitting parked also age the shocks? Yes, I have seen shocks leak from sitting too long (years) so I assume some seals deteriorated... B Link to comment Share on other sites More sharing options...
TerranoMW Posted January 23, 2010 Share Posted January 23, 2010 One of my brand new KYB GR-2's broke (!) after just a few weeks - the part attached to the top mount just snapped. The mechanic ended up having to weld it back together - not a good look . . . That being said, my car only knows rough dirt roads and rarely sees pavement - but I never thought it was possible. Anyway, they've held now for a few months. Keeping my fingers crossed. Link to comment Share on other sites More sharing options...
Precise1 Posted January 24, 2010 Share Posted January 24, 2010 I'm new to the R50s but I could have sworn I read something about the KYB upper mount (bearing portion) was bad news and should not be used? Perhaps that contributed to the break? Damn, now I have to go try to find what I read... B Link to comment Share on other sites More sharing options...
jpawela Posted January 24, 2010 Share Posted January 24, 2010 I'm pushing it on my wd21. At nearly 130K, I'm still on the original shocks. They are so soggy-feeling in "comfort" mode I have to have it in "sport" all the time. Link to comment Share on other sites More sharing options...
adamzan Posted January 24, 2010 Share Posted January 24, 2010 My 95 had the original shocks in the rear when I got it and at 160k when I changed them they were still stiff as a board (XE non adjustable) but the mounts were starting to rust.
