Well my rear shock is gone. It compresses but returns way to slow. I called my dealer and they will not warranty it because it is just out of warranty, and they said shocks are not usually covered. However I contacted fox directly and found out that their shocks have a 1 year warranty. So if they find that it was a failure and not abuse they will fix it free of charge. The service center I sent it to will also revalve it for my weight and riding conditions, however the revalving I have to pay for $17.00.

Just thought I would share some info with you guys, and maybe help someone else save some money.

 

well,
i know you have a bigger shock then my 95'
but here is my problem, well its not reall a problem
i lowerd the shock so i would get a better ride when hitting bumps, but when i, or anyone gets on it, it goes down a few inches, and i hear a rubbing noise once in a while, i think its a tire, but anyway the quad goes down to far.....
about the gas resovior, how many psi is that supposed to be??
can i fill that with any compressor, or is it special air,
and i am going to raise the shock again

 

the shocks are filled with nitrogen. The psi will depend on your weight and riding condition. However you may want to look into having it rebuilt and revalved for you and the way you ride.
Carver Performance rebuilds and revalves to your weight and riding conditions for $47.50 if they need to change the piston it's another $11.00.

If you just need it recharged take it to a local bike shop they should be able to do that for you. It should be around $10 - $15.

But if you want it lowered i would suggest a rebuild and revalve and get it set up right.

 

Bubba, I have a 99 Scrambler 400 4x4 with the same problem. Do you have a telephone number or URL for Fox? Did they indicate what the failure might have been? Thanks!

 

They are working on it today and I should be contacted either today or tomorrow with the findings.
But because yours is a 99 it probably will not be under the 1 year warranty. Their is no defect in the shock that I know of it is just that mine failed 6 1/2 months after I bought it. They haven't said it would definetly be covered, but if they see that it failed under normal riding conditions and not neglect they will honor their warranty. However if it is neglect I will have to pay for the rebuild.
Either way I still have to get it fixed or by a new one. I think when it gets revalved properly it will be better than new.

Anyway if you want to try the # is 800-fox-shox

 

Well it turns out that a rubber piece on the rebound part blew apart and caused the valve to plug up not letting the shock return.
This was covered under fox warranty!
Just thought I would let you guys know.

 

kukerdan,

The rubbing you hear is from the large 25" rear tires you have. The stock 22" rears don't have that much clearance, so I can imagine how a 25" tire would rub. Stiffening up the preload is only a temporary measure. It might not rub now, but if you ever hit a nice sized bump it'll come back with a vengance.

The nitrogen in the shock is NOT user servicable and wouldn't affect the ride quality anyway. The nitrogen is placed in the shock (under 250 PSI of pressure) to keep the oil from forming tiny bubbles known as cavatation. These tiny bubbles really mess up the valving if they are allowed to get into it. It would seem like there is no dampening in the shock as air can be compressed but liquids can't. The pressured nitrogen prevents these bubbles from forming. DO NOT USE COMPRESSED AIR. Compressed air has oxygen in it, which is bad for the internal parts of the shock (that is assuming you could find an air compressor that would pump up to 250 PSI).

The shock lowering a few inches while sitting on it is a good thing, this is called sack. As long as the rear suspension isn't sacked out more than 1/3 of it's travel, you'll be fine. If it is more than 1/3 of it's travel, then bump up the preload until it doesn't sack out so much. This sack is needed to help the distribute the weight and help steering.

 

It's not the oxygen, it's the moisture in the compressed air. Causes internal corrosion. Nitrogen is dry and pure, that's why we use it in our jets.

modquad,

I forgot about the moisture. Yes, that isn't a good thing to have in a shock either. Plus the nitrogen is an inert gas. I stand corrected.

 

thanks flearing that up, no, it didnt sag over 1/3,but the rubbing was getting to me, i tightened it up not much sag now, but its good againj, do the front fenders have more clearance, cuz as u guys know, i need to put 25'ers up front + new rims, i want 7/8 inch tire width aND, good traction and handleing, godyear trackers/mudrunners? what size and what rims?
thata alot safere then 23's up there for the awd, i cane up with twosolutis, if you guys canhelp, cause there is no reasonable way for me to find out,
#1: put tall 25's up front (is therea tall 25? AND IF SO ONE THAT MEETS MY NEEDS?) THIS WOULD BE PERMANATE...

#2: PUT 25'S UP FRONT, ANDWHEN I HAVE TO REPLACE THE REARS, PUT 24'S, IM GETTING A MOOSE SKIDPLATE TO.,
PLEASE ANSWER, THIS WEB T KEYBOARD AT THIS HOTEL IS ANNOYING, AND CAPS WOULDNT GO OFF, SO I DESERVE IT,
THANKS
DAN
(caps finally webnt off)
