How fast can I go with the rear driveshaft off?

 

if your front end is in 100% perfect working order...probably around 65mph or so safely..

i drove my old '02 dodge diesel 4x4 up through 100mph in 4wd...(don't judge me....lmao) and although it's a totally different vehicle COMPLETELY....the 4wd HI is supposed to work at highway speeds just fine.

 

Wow, what a quick response, you guys! Cool. I just want to take it up to 70 real quick and check for vibrations.

 

I dont see any reason why if everything is balanced more or less correct, you cannot take it up to whatever speed you want.

 

i was cashing somone down a dirt road one time and he ran me off the road down about a 6 foot drop into a cornfeild, my u joint broke on the back driveshat so i took it off completely and drove it home in 4hi.

4hi is geared the same as 2hi, so your pretty much in 2hi with front wheel drive

 

I ran at 70mph from Portland to Tacoma (150miles) with a square front Once

 

that sounds like a good time!

My friend drove his 1st gen around town/upto 65 mph for weeks with only front driveshaft.
