1994 Yamaha Big Bear - Rear End Torquing First

[bowhuntr77]

when i give it gas the rear end will torque up like the front brakes are engaged, but theyre not. giv it a little more gas and all is good. is there a problem?

[swampcat07]

Is it a 4X4 or just 2WD?

[bowhuntr77]

4x4

Make sure your tires are the correct size and the air pressure is the same. It may be stuck in 4X4. Can you take it for a ride and see if the front wheels are grabing.

my 1990 bear 350 does the same thing

I consider it normal and my front brakes r not locked up

its all time 4x4...but it does have a low tire....not sure if they are the correct factory size. these are aftermarket tires and were on there when i bought it.

As long as all 4 are the same size abd pressure you are ok. You can also measure all of the tire heights. If the fronts or rears are alot lower than the otherone then the ratio is diffrent. The front will want to spin faster/slower than the rear. Just a starting idea.

I would also check the diff fluid and see what color it is and if there is any metal in it. I always start with the cheap ways to check first.

With all time 4x4, swampcat is correct. Tire pressure and size is crucial. If someone put tiny tires on the front & big tires on the back, then it's binding the driveline. A low tire will also create problems. I'm sure the front diff is open but is the rear solid axle?, or IRS? I'd focus on tires and pressures first, then if that checks out ok, check the front diff & or brakes. JMHO.

My friend eliminated diff problems with a fluid change. I don't think there is anything major going on here.

its has fresh fluid in it...i just finished replace both outter cvj's and had the half shafts out. the fluid that came out of the front diff was extremely clean...i was impressed and relieved when i saw it. the rear axle is solid. i did not check tire sizes last night when i got home. ill check tonite though. what kind of slime do yall recommend filling the tires with

i'm pretty sure 25" tires were stock on those machines with 12" rims. as long as all the tires are 25's or 26's or 27's, you should be good to go, but take swampcat's and mudflaps advice on the tire pressure. i used a radial tire slime for my bike ....

It should be normal for a little drag then. Heck my 2012 can am has a clunk in the clutch and so do all the other models, I guess they are just normal operating quarks.
