How do you change the handle direction, we have the small wheels at the rear and would like them to be at the front

Two wheel drive high range, Please check the drivers manual. All will be explained there.

The small handle attached to the hand wheel is the problem:
1. Loosen a small screw on the front or side of the small handle. Almost all the way.
2. Tighten the small handle as if you are tightening like you are going from loading a bobbin to sewing.
3. Tighten the small screw.

You mention front and rear wheel bearings have no play, but have you replaced them? I do remember part customers replacing the wheel bearings on the gl1200 at about 10,000 mile intervals because of what you describe. You do not mention the miles on the motorcycle but I think that if you replace the front and rear wheel bearings you will notice a huge difference in how your Gl1200 handles. I do not think it will be necessary to do anything with the final drive bearings. Remember to regrease the spline on the final drive with Moly60 grease before reinstalling the rear wheel. I have replaced the wheel bearings on my GL1000 ( around 125,000 miles) several times and handling always improves.

Depends on what model and components you have:

ENGINE TORQUE DISTRIBUTION – DIRECTING THE FLOW OF POWER
In an all-wheel-drive vehicle, engine power can be directed to all four wheels. Subaru Symmetrical AWD differs slightly from model to model in how it directs power to the wheels, depending on its transmission.

MODELS WITH FIVE-SPEED MANUAL TRANSMISSION – CONTINUOUS ALL-WHEEL DRIVE: A viscous-type locking center differential and limited-slip rear differential help distribute torque – normally configured at a 50/50 split front to rear. If wheel speed differs between front and rear axles, the center and/or rear differentials lock up to help distribute power to the wheels with the most traction.

MODELS WITH FOUR-SPEED AUTOMATIC TRANSMISSIONS – ACTIVE ALL-WHEEL DRIVE: An electronically controlled variable transfer clutch and limited-slip rear differential distribute power to where traction is needed. Sensors monitor parameters such as wheel slippage, throttle position, and braking to help determine torque distribution and direct it to the wheels with optimum traction.

MODELS WITH FIVE-SPEED AUTOMATIC TRANSMISSION – VARIABLE TORQUE DISTRIBUTION ALL-WHEEL DRIVE: As with Active All-Wheel Drive, an electronically controlled variable transfer clutch distributes power, but through a planetary-type center differential and a viscous-type limited-slip rear differential. Torque distribution is normally configured at a performance-oriented rear-wheel-biased 45/55 split front to rear. Sensors monitor the same parameters as for Active All-Wheel Drive.

WRX STI, WITH SIX-SPEED MANUAL TRANSMISSION – DRIVER CONTROLLED CENTER DIFFERENTIAL (DCCD) ALL-WHEEL DRIVE: The STI uses an electronically managed multi-plate transfer clutch and a mechanical limited-slip differential in conjunction with a planetary-gear-type center differential to control power distribution between the front and rear wheels. Featuring manual and three automatic modes, DCCD is normally configured at a 41/59 split front to rear. Sensors monitor parameters such as wheel slippage, steering angle, throttle position, and braking to help determine torque distribution and direct it to the wheels with optimum traction. DCCD also features a limited-slip helical front and Torsen® rear differential. ... }

And what are the symptoms? How do you know the coupling to the rear is not working?

many things can cause this ,if you change your seating postion ( lean forward / move backwards does it go away?....

front forks loose at triple tree,
new front / rear tire more aggressive tread than before,
front wheel loose,
worn head bearings,
bent rim,
loose spokes if any,
wrong tire pressures,
loose handle bars
,some new addition to change the handling of the bike , rear seat rest etc,

These strollers are made to only go straight for running,it is hard to use them any other way.

You cannot rotate front to rear because you have 17in 225 50's on the front and 235's on the rear. The rear tires (and wheels) are slightly wider than those on the front. You can get all the same size...225's if you replace the rear wheels. When you see the price of those wheels, you'll probably continue to purchase tires. You could get a tire with better treadwear..(harder compound), however you will sacrifice ride and handling and probably noise. I would not recommend side to side rotation because unless the tires are remounted and rebalanced, you will change direction..not recommended on radials.

The following is from the instruction manual for the Expedition LX. It should be very similar to the Expedition LE.

"Stroller pulls to one side:1. The stroller is sensitive to the air pressure in the tires. If the rear tires do not have equal pressure, the stroller will feel like it is pulling to the side with the tire with the lower tire pressure. Check that the rear tires have the same pressure. Add air pressure to a maximum of 25 pounds using a bicycle style hand air pump.2. The alignment of the front wheel of the stroller can also cause the stroller to pull to one side. The stroller is designed so that the front wheel can be adjusted to correct for any alignment problem. Page 3 of the instructions
shows an expanded view of the front fork assembly. To align the front wheel, first loosen the wheel via the quick release handle as in step 2 of the instructions. Grab the front wheel directly in front of the stroller and push the wheel in the opposite direction of the pulling problem. You will notice that the axle will move within the slot on the fork. Move the wheel to the side a small amount. Retighten the quick release handle. Give the empty stroller a push across an empty smooth surface (let go of the handle) and note if the stroller now runs straight. Re-adjust the axle a small amount at a time until the stroller runs straight. Please note that a very minute
movement of the axle will affect the tracking of the stroller. Once you have aligned the front wheel, you can mark the holding plate position with a marking pen if you detach the front wheel on a regular basis. Please note that the hole in the fork is designed to allow the stroller to be adjusted to pull to the right, go straight, or pull to the left. If you continue to have difficulty with tracking, please call our customer service department at (800) 328-7363 for assistance."
