How to change awd into rwd on 1991 toyota previa

No, Most front wheel bearings are sealed bearings. you have To change the whole hub, because the bearing is pressed in. God-Bless you and your family!

sorry but google really does work.

pop fuse cover, remove vent housing, remove speedo upper cover, remove 4 bolts holding speedo remove speedo, change bulb

a burnt/seat valve could also be the cause of smoking

by slip -yoke for rear drive shaft, I think you describe a spline joint with universal joint yoke attached, I have all drive shafts for an AWD previa. Write [email protected]

The Previa has a special hydraulic center clutch. To convert it to rear wheel drive it would be necessary to replace the whole drive train. Disconnecting the front drive shaft on a 4 wheel drive vehicle will only save you a very small amount of of fuel. The only way to see a substantial fuel savings is by disconnecting the front drive axles from the wheels. This is what manual hubs do and that is why they are still popular.
To see even more fuel savings you would need to remove all of the front drive components and this would remove several hundred pounds and ever bit of weight that you can remove adds up to more fuel savings. But now you will end up changing the center of gravity and the balance of the vehicle.
I have made the assumption that you are trying to increase the fuel mileage of your Previa. Is this correct??
So in the long run you are looking at a major rebuild of your Previa. It would be less costly and less of a headache to go buy a smaller more fuel efficient vehicle.
I know that this isn't the answer you were looking for but this is the proper answer. I hope this helps.
Thanks,

I do a lot of work on Toyota Previa before; including rebuilt engine, swapping engine and transmission and lot of things in between, but never swap a normal aspirated engine to a supercharged engine or diesel. Since i have some experience in Previa, I would like to share my opinion with you regarding your plan to swapping the normal aspirated Previa engine to a Supercharged engine. When you do a swapp like that, you will not only be dealing with just swapping engine, but some wiring, computer, throttle body, air cleaner assembly, extra frame and pulley on the accessory items, transmission as well as a right rear end to get the correct gear ratio to accomodate the new engine and transmission. I can go on even more, but let me tell you this, beside less headache, it would definitely cheaper if you were to find a Supercharged Previa and fix it up. However, if you are totally motivated to do this project, keep in mind, this engine swap will be a long term and time consuming project.l I wish you best of luck and have fun!
