OK--so the rear end on my new whines really bad so i took out the rear drive shaft and shifted into 4wd. I am now in front wheel drive. Question is--without the rear shaft connected--what speed can i reasonable go and not hurt tranfer case/front end?

And dont worry--this is only temp--i have 4.88's on the way

 

There have been threads on this before. It seems the general consensus is it won't hurt anything.

Should be ok, a friend of mine did 35mph for about 12 miles fine.. Take it easy..

 

How could it? There is less load on the components.

 

Drive it easy, speed is not a factor, and you should be good to go.

 

I've driven in FWD at highway speeds around 70-75mph without any problem. I had the rear drive shaft off for a little while. That was with Marlin crawler t-cases.

 

It wont hurt much is pretty much what i thought. There would be no other component to push pull against--i was figuring that was the major issue when you are in 4wd with both shafts in. All seems fine and i dont get any weird vibrations so i guess i will stick with it. Hopefully my gears are done soon.

 

just dont try to drag race it in fwd and you should be fine.

 

watch the heavy acceleration, it's hard on the tcase chain with no rear drive helping...

 

It drives differently too. Takes a little getting used to.

 

around town, should be alright, but i wouldn't take it on the highways.

 

Is the rear 3rd member still in it? My wife drove her 92 4Runner for weeks in FWD,she didn't tear it up,you wont either.Use your parking brake,hers would jump out of FWD overnite,and be in the edge of the woods the next morning.You've been warned!

 

PS ,My rear has been whining for years(7-8 years)with no problems.

 

would have to be, if not hes not going anywhere, those axle shafts will just find their way home with the drum and wheel attached. rolling missles down the highway with semi float rear.

 

I wouldnt worry too much about it. Me and my buddy are building up a bronco 2, it had a broken rear U-joint when we first got it so we drove it in 4x4/FWD for the first few days when we were testing it to find out what we needed to replace. I reached speeds around 50-55 without any noticable issues.

 

I was riding in my friend's lifted F*rd Exploder, and the rear driveshaft fell off. He removed it from the back axle and drove it around for 3 days. It did a pretty sweet front wheel drive burnout with 33's.

My opinion: Do as many reverse donuts as possible while you still can.

 

i would just stay off the highway and easy driving and you shouldnt really hurt anything.

 

Yeah, but i hate that noise--annoys the hell out of me

Well in response to all--it seems advice is all accross the board. I drove on the highway at speeds and it seemed to work alright--if it craps out--it craps out--I will be the lab rat for this one

 

This advice makes the most sense to me. Heavy acceleration or load would be more of a problem than the speed with a chain driven t-case, if thats what you have. My t-cases are gear driven.

 

I drove about 60 miles in my 73 Blazer after breaking a rear ujoint at about 50 to 60 mph no problem
