Hey everyone-

I was wondering- how do you know when you need to change the bearings/bushings on the quad? How many bearings/bushings are there on a 400ex?- where are they? Is there any maitenence that should be done on the bearings?

Thanks for the insight!

 

If you mean suspension bearings, you shouldn't hafta change them for quite sometime. I don't have an EX to look at right now (my friends took theirs home), but if its got grease fittings on the A-arms or Swingarm, give them a few shots of grease every other ride or so, if not once or twice a year strip them down and pack some good ol heavy duty mining-grade grease in them (don't use on wheel bearings-not a high speed grease) Oh, grease them more often if you ride in water alot.....P.S. I just replaced every suspension and wheel/axle bearing on my Zilla cuz the previous owner didn't believe in grease, and cost me just about $700....most were Pivot Works kits, but the cushion lever was all Suzuki O.E., so take the time to use a 2 dollar tube of grease......

 

Oh yeah, grab right ahold of the A-arm right by where it mounts to the frame and shake the hell out of it-if there's any play, the bearings are probably bad.....do the same for the front wheels, Swing arm, and rear axle....Latah

 

i change the axle bearings in my 400ex about every 2 months

 

Why would you change axle bearings every 2 months?

 

It seems like once your bearings go out, it's hard to keep new ones tight.

 

hey,
about every 4 months mine go out in my 300ex but the most part is i run nothing but roads every day and whan im not imn in mud or on a track.

 

MY SON PUT THAT FIRST MESSAGE IN WITH OUT ADDING THE WHOLE STORY. YES WE CHANGE BEARINGS EVERY COUPLE OF MONTHS BUT WE ALSO RIDE 3 TO 4 TIMES A WEEK IN THE MUD AND TIMBER. CONSTANT TORQUE AND A LITTLE BIT OF GRIME TAKES BEARINGS OUT FAST. IF I FEEL THE SLIGHTEST BIT OF MOVEMENT IN THE AXLE THEY ARE CHANGED.ITS MUCH CHEAPER THEN AN AXLE.
