If you've started hearing that irritating clicking sound whilst turning or rising, your 2009 yamaha grizzly 550 rear cv axle is probably on its last legs. It's one associated with those things each Grizzly owner relates to eventually, especially if you actually make use of your machine for what it was built for—getting muddy and climbing over stuff that probably shouldn't be climbed. The 550 is a workhorse, but like any ATV along with independent rear suspension system, those CV joints take a conquering each time the suspension system flexes.
Whenever an axle begins to go, it's usually not a "maybe" situation. You'll know. Whether it's a torn boot that let a bunch of grit into the bearings or just high-mileage wear and tear, disregarding it usually leads to being stranded in the center of the woods along with a wheel that will won't turn. Let's get into what you should know about changing out that rear axle so you can get back again to riding.
How to Inform your Axle is Performed
Before a person go tearing the particular rear end of the Yamaha apart, you want to be sure it's in fact the axle but not a wheel showing or an unfastened lug nut. The most common indication of a faltering 2009 yamaha grizzly 550 rear cv axle is a rhythmic clicking on or popping sound. You'll notice this most when the suspension is compressed or when you're under a heavy weight.
Take a look at the rubber boots. If you see grease splattered all over your own rim or the A-arm, that's the dead giveaway. As soon as a boot holes, the specialized fat inside flies out there, and water and dirt get in. Once that happens, the CV articulation is basically sandpapering itself to death. You might furthermore feel a weird vibration through the seat or floorboards whenever you're cruising with higher speeds. If the axle has actually snapped in the boot, the device might still move if you're within 4WD, but you'll hear an unpleasant grinding sound from the rear.
Choosing the Perfect Replacement
You've got a couple of options when it comes to purchasing a new axle. You can move with the OE Yamaha part, which is usually high quality but comes with a price tag that may make you wince. Then presently there are the auto aftermarket options.
The 2009 Grizzly 550 shares plenty of DNA with the particular 700, which is great because components are everywhere. A person can find "heavy-duty" axles that claim to be stronger than stock, which usually is a great move if you've added a lift kit or huge, aggressive mud auto tires. If your Grizzly is mostly share and used for trail riding or farm work, the standard replacement axle will do just fine. Make absolutely certain you aren't purchasing the overall cheapest thing upon the internet—some of those "budget" axles have boots made of plastic that'll break the 1st time it gets cold outside.
Tools You're Heading to Need
You don't need a full mechanic's store to do this particular, but a few particular tools will make your own life a lot easier. You'll need a good jack port and some stands— never work upon a machine kept up only by a floor jack.
Grab the 27mm socket (usually) for the axle nut, though it's always smart in order to double-check your specific nut size. You'll also need a variety of sockets with regard to the A-arm mounting bolts, a pair associated with needle-nose pliers with regard to the cotter pin number, and a big pry bar. A rubber mallet is also a godsend for when issues are stuck, and they almost always are on a machine that's been via the mud. Oh yea, and get some rags. This is going to be unpleasant.
Tearing It Down
Initial things first, release the axle nut while the tire will be still on the floor. That nut is torqued on there fairly tight, and wanting to break it loosely while the bicycle is on a jack is a formula for a tipped-over ATV. Once it's loose, jack up the rear, draw the wheel off, and remove that axle nut the particular rest of the way.
Next, you need to get the particular hub taken care of. Usually, you can just pop the top or lower A-arm bolt out to let the knuckle swing away. Be cautious with your brake lines here; a person don't want them stretching or kinking while the hub is definitely hanging. Once the particular hub is apparent, a person can slide this off the splines from the axle. In the event that it's stuck, provide it a few shoes with that silicone mallet. Don't use a metal hammer unless you want to mushroom the ends associated with your old axle (though if you're throwing it aside, I guess it doesn't matter as well much).
Taking the Axle From the Differential
This is actually the part where individuals usually get discouraged. The inner finish of the 2009 yamaha grizzly 550 rear cv axle is held into the differential simply by a little round spring clip (a C-clip). To obtain it out, you need a quick, sharp tug.
If it doesn't want to budge, don't just draw harder and tougher; you might turn out pulling the axle right out associated with the inner CV joint, leaving the particular "cup" still stuck in the difference. Instead, use the pry bar among the differential casing and the axle cup. Give this a fast flick. You're wanting to compress that little clip so it slides out. Just be cautious not to mumbo jumbo up the oil close off within the differential whilst you're prying.
Installing the New Axle
Before you slip the new 1 in, take the second to wash away the splines inside the differential. Apply a small amount of waterproof grease to the splines of your new axle—this may make it the lot easier in order to get out the next time (and presently there probably will end up being a next time).
Fall into line the splines and give the axle an excellent shove. You should listen to or feel the "click" when that will C-clip seats straight into place. Give this a little tug out to ensure it's locked in. If this slides right back out there, it's not sitting down, and it will fall away on the trail, which usually is a great way in order to ruin your weekend break.
Putting This All Back Together
Slide the particular outer end of the axle back into the hub, bolt your A-arms back again up, and obtain that will axle nut on. It's a smart idea to make use of a new cotter pin—don't reuse the rusty one. Torque the axle nut down to specification (usually around 180-190 ft-lbs, but verify your manual). If you don't have a torque wrench, it requires to be "he-man" tight.
Put the wheel back on, lower the Grizzly, is to do a final check upon all your bolts. It's the smart shift to look at your differential fluid level whilst you're back right now there. Sometimes a little bit leakages out if you pull the axle, and it's preferable to best it off right now than to burn a diff later.
Making Your Axles Last More time
If you're sick and tired of replacing your own 2009 yamaha grizzly 550 rear cv axle , there are usually a few issues you can do to stretch the life of the new one. First, watch out for "boot sticks. " These are literally just sticks that get kicked up plus poke an opening in your CV boot. Installing some aftermarket A-arm protections can act because a shield and save you a lot of headache.
Also, be conscious of your browse. High-stress situations such as "full-throttle-full-climb" or "pinned-in-reverse-while-turned" are exactly how axles snap. If you're stuck in strong mud, try to avoid "bouncing" the bike while the tires are usually spinning. When these spinning tires all of a sudden catch grip on a root or rock, that shock weight goes straight in order to the CV bones.
Wrapping Up the Job
Replacing an axle isn't exactly a fun Saturday afternoon, but it's an essential skill if a person own a 2009 Grizzly 550. It's one of these repairs that feels intimidating the first time you do it, but once you've done one particular, another three edges of the machine appear a lot less scary.
The Grizzly is a legendary platform for any reason—it's tough, reliable, and relatively easy to operate upon compared to some of the more complex contemporary machines. Keep an eye on all those boots, listen with regard to those clicks, plus don't hesitate to get your fingers dirty. A new axle means you can head away for the trail with the confidence that will you'll can even make this back to the particular trailer under your own own power. Joyful riding!
