Sounds like tuning problems.
Yamaha cautioned on this.
First, make sure the engine remains in a good state of tune, valve clearance, carb sync, idle speed (STOCK, 1000~1100 rpms) idle mixture.
Then starting procedure, full choke no throttle when cold, do not try to rev it until the engine gets some heat in it.

How do you remove the front drive shaft in a 1995 jeep grand cherokee limited

Use white paint, chalk or a scribe to mark the relationship of the front U joint to the front diferential pinion yoke. Mark the relationship of the rear U joint flange to the transfer case companion flange. Unbolt the front end of the drive shaft from the pinion yoke and the rear end from the transfer case companion flange and remove the drive shaft from the vehicle.
hope thei info helps.

Pontiac G5. Steering wheel spins freely, wheels don't turn. Is this a U joint issue?

either the steering shaft has broke or the rack and pinion is broke have someone turn the wheel and look under hood near where the steering shaft meets the rack and pinion. do you see it spinning? if so the rack is most likely broke inside. if not the steering shaft may have snapped. hope this helps

2008 FLHX With flywheels inside cases the bushing surface of the pinion shaft shows a runout of .006 With the flywheels on the truing stand the pinion shows a runout of .0005 and the sprocket shaft has a...

Ok, I thought I answered this before but now I see something that I failed to see before. You say the "bushing surface of the pinion shaft" shows a 0.006" runout while in the cases. At first, I suspected a bent pinion shaft but now there is another possibility. The "bushing surface" that you are talking about is all the way out on the end of the pinion shaft. It runs in the bushing that is in the cam cover.

The first thing I'd do is measure the end of the pinion with a standard micrometer three times each at a different angle to see if the end of the pinion is indeed round. If the pinion shaft was not properly hardened, unevern wear of that portion of the pinion shaft could occur. Of course, the pinion bushing in the cam chest cover would be worn as well.

You asked if the pinion bearing or cases could be the cause. Well, I guess anything is possible but the only way to tell is to check the align bore of the cases. It's best to take the cases to a machine shop that has the tools to check this but if no shop is available and you have the tools, you can do it. You'll need the "lapping tools" for lapping the pinion bearing. First use a magic marker to "color" the pinion bearing race. Bolt the empty cases together and torque them. Now, install the lapping tool in the races for the Timken bearings. Insert the lap into the pinion bearing race and tighten the lap until you bearly feel it touch the race and turn it a time or two. Take it out and see if it took the color off the race all the way around. If not, I'd go ahead and lap the race for the next oversized rollers. Then, you know it'll be right as far as the cases go.

Now if the pinion is bent, you can no longer trust the reading you're getting from your truing stand. The truing stand that Harley suggests using uses two 'dead centers" that sit in center drilled ends of the pinion shaft and the sprocket shaft. If the pinion is bent, this screws up the "axis" these centers are on. Put the assembled flywheel in a pair of "V-blocks" and check the entire length of the pinion to determine if it is bent.

Good Luck

Got a leak from the rear differential on my truck, where the drive shaft goes in what made it leak

Hello Barry.
There is a flange attached to the pinion shaft that drives the gears inside the differential.
This flange is held to the shaft by a large nut threaded onto the pinion shaft.
On the flange there is a machined surface the seal rides on to retain oil inside the differential.
Sometimes rust can develop on this surface and tear the seal. Also debris could damage it as well.
Or in a worst case scenario the bearing that the pinion shaft turns on goes bad and allows the flange to wobble.
It will take an experienced mechanic a little over an hour to replace the seal.
The large nut on the pinion flange needs to be properly torqued and takes a proper torque wrench to do it.

Thank you for using FixYa.

My impact driver is not this model its a dc827 but it quit hammering it just free wheels if you just slightly pull the trigger is kinda works is there anything i can do to fix this prolbem?

The pinion on front of motor is slipping on motor shaft. It seems to be just a press fit. Seems like a flaw in design. I had same problem. I took my dw056 apart and took pinion off motor and pressed groves into motor shaft with side cutter pliers. then pounded pinion back onto motor shaft. We will see how long this lasts the motor shaft is a softer metal. I feel the motor shaft should be hardened steel like the pinion and have a shear pin or some sort of spline to attach to pinion. Would like Dewalt to offer fix for this as I only used dw056 a couple of times before I had problem.

Rear axle vibration

If you have that much play in the pinion, your pinion is getting worn, or the nut is loose. You may be able to find a rear end at an auto wrecker cheaper than anything.

How to replace front drive shaft ?

Mark the drive shaft postion to the transfer case and front axle. Remove the bolts/straps from the transfer case and front axle pinion that hold the drive shaft in place. Remove drive shaft. You may have to drop the exhaust pipe for access.

Purchase part

If the threads are not stripped on the knob or shaft, just screw it on clock-wise.
If the threads are stripped on the shaft, it must be replaced, same with knob.
To replace the shaft (if the knob is off) just pull it down in the film compartment. now there is a spring to hold the shaft up or down if the new shaft has a beveled shoulder just turn the shaft while pushing it back up. If no beveled shoulder is on the shaft then with a long needle or pin hold the spring back while pushing the shaft back up. Don't bend the spring. just move it out of the way.
