Driving without rear driveshaft

Drove to school today without any problems so hopefully I'll be good till my shaft gets done

 

You'll be fine. After going through 5 rear driveshafts on my old Jeep I finally said eff it and drove it for the next year and a half in front wheel drive. This was back in the high-school/college days. Starving student ain't got time for that. Bit of torque steer was the only noticeable difference.

 

Is the torque steer any worse than a FWD car?

 

Torque steer feels a lot worse than any car I've driven, probably cause of the 33's if I had to guess

 

Boom new one piece shaft, $183

 

Exactly:

Done this many times. Might have a truck on the lift and remove the driveshaft to ( maybe get a light-weight one made) let the truck down and put it in 4x4 and drive it outside.

But CAUTION: This only works, if the yoke at the transfer case output is attached to the output shaft of the transfer, usually with a big, torqued, nut. His 1st gen truck has the bolt on yoke, he is good.
If there is a slip yoke at the rear of the transfer, (NO NUT), when you remove the driveshaft, and the slip yoke pulls out of the transfer, your transfer fluid will be able to run out. Only a little will come out, because that is the high point; but if you drive it, the fluid will run out; because the yoke is not against the transfer rear seal.

It all matters how the yoke is designed; trucks come both ways. OK


As for the binding: There will be No binding if the front differential, is not a fully lockable one, as the TRD OFF Road rear differential with the Lock feature. And his 1st gen did not come with a fully lockable front differential.

Anyway there would be no binding in the transfer because the rear driveshaft is removed. Once the driveshaft is removed, there can be no binding in the transfer.

Yes. Because the truck wasn't intended to be driven in FWD, Toyota made no attempt to minimize torque steer through suspension geometry (reducing scrub radius), or sizing the CV shafts so they flex the same amount.

 

Gotcha. Makes sense.

 

Drove the 110 miles round trip to get my shaft today, got home and it's only got about 1/4" until it's bottomed out so its gonna stay out till this weekend when I swap in the 5 speed and free up 2 1/2 inches. Also, truck vibrates a little at 70 probably from an unbalanced front shift? Or maybe transfer case slack

 

In an absolute dire situation you could do it (I.E. you lose a u-joint on the trail and need to get home or to the nearest repair shop) but actually just driving it for any length of time is not a good idea.

 

Why?

 

Seems fine to me

 

I realize my previous statement of being "locked" was wrong (omg someone admitted? ), had a brain fart about xfer/diff

but driving with only the front at 70mph is

 

Try this experiment - put your truck in 4WD and attempt at turning into a parking spot. By the time you make it into the spot, your new driveshaft will be ready for pick up!

 

Ive had to drive a Toyota like this after my driveline blew up...I drove it a couple miles to the gas station and that was the end of my front wheel drive toyota experience...

 

That's not the situation we are talking about here.

The reason you get binding in that situation is because the one front and one rear wheel have to turn at the same speed. Since he has his rear driveshaft removed, this is no longer an issue.

 

Unbalanced front dshaft. Since they're not intended to be used all the time at all speeds like a rear shaft is most companies don't balance them.

 

You know, from the amount of time I've owned jeeps you would think I would remember about the rear slip yoke One of the I'm sure cost saving measures that they used in building the tcase that can cause a lot of problems in the right situation. I've never needed to try it but supposedly a 20oz coke bottle is about the right size to make a handy plug as a trail fix.

 

Ok and it turns fine no binding what so ever, no locker is the front diff nor posi, as has been said the binding in 4wd comes from one rear wheel and one front wheel turning different speeds.

 

Hahahahaha yeah, I'm not too careful with my truck. Kinda reckless actually, rev limiter 4wd on 3 cylinders coming out of a mud hole kinda reckless.... Then drive 20 miles home misfiring like crazy. Gotta hand it to the old truck tho, still runs great and gets 18 mpg now
