Broken Driveshaft.

You should be good with the 2".

Thanks Dirttrack.

We took a long driveshaft we had to a truck parts store/shop and they cut it down, balanced, and put in new u-joints and painted it for $65

Thanks for the info guys. One other question. How do you determine the driveshaft length. Lets say at ride height , my length from center of rear u-joint to the center of front yoke is 53" with the yoke pushed all the way in the tranny. When i raise my car up on the lift, this distance only changes about 3/8" at most and thats when the suspension is hanging way down. How much clearance do i want between the yoke and the tail housing where the seal is ?Is there a set amount. Thats the last thing i need to figure out before trying this again. Thanks for any info.

If your yoke can go in inch and out an inch with no problems you are OK.

Carolina Driveline also specializes in these. That's where I've bought my last two.

driveline specialist an stone heavy duty in g'boro can fab up any type of shaft you can imagine!!

1.5 is the MAX you would want sticking out on a stock yoke.

pinion angle, not sure where you get your ideas from, but your wrong. you might want to read about drive shafts, u joints and such and then youll learn what your pinion angle should be at. Its not a guessing game.

splicer web site,...an lots of post on here! as i said,depending on type of suspension to,..if his suspension moves rearend forward more than 1 1/2 he gotta have more yoke slide,..basic physic's 2 objects of matter cant occupy same space at same time...cant argue with sir isacc newton can ya?

Im not sure if you are even using english in the above post?

BUT to clarify with a oem slip yoke the MOST ANYONE should have exposed is 1.5.


As for using posts on here as a reference, thats just laughable based on your own BEING incorrect when it comes to pinion angle by a MILE!

he posted he had just installed a longer than stock yoke in his first post,....correct me on pinion angle then,..been tryin to get it straight in my mind as im puttin motor,trans an rear end in miner for first time an need to get it right!,..an had thought i had a good grasp of it all threw posting threads an studing your an ego an others replys to them...

quot...According to Bickel, a ladder-bar suspension normally requires ½ degree of pinion angle, a four-link requires 1-2½ degrees, and a leaf-spring suspension requires up to 6 to 7 degrees.

Nice to see you doing some research and educating yourself. Taking a persons word on a forum is not always the best way to go. Now that you did some looking Ill tell you my opinion.

In my opinion the numbers you quoted above are what they believe the pinion needs to be at in order to make sure it doesnt over center and they are taking into account some extra security... or extra angle a little.

I run NEW rear bushings and maintain them well and run the same pinion angle in my rearend as I have ANGLE in my motor. In other words I match the two u joints angle so as to not lose HP by having a bind in either or both joints!

My motor is mounted LEVEL at ride height all scaled etc. My pinion is ZERO in the car.

My motor is 1.25 angled down compared to the frame if the frame was dead level. I run the rear of my car a little higher than the front most of the time is the only reason there is any angle.

done researched it till my head hurts,..have no clew what ride hights will be,..got frame level!! all i can find has pointed to 4 to 5 degrees down on motor,...an 6 down on pinion,full camaro clip-tube back, on leafs...with stock type solid motor mounts,...now im confused again!! hell tryin to build a dang car with no experience,no help,an sadest,no money!! all my experiences with drive lines has been in tandem axle big trucks an i know what it takes to get them to live runnin flat out tote'in 80,000lbs! but thats a total defferant world than a dirt car!

leaf cars do require negative pinion angle to prevent going past center, normally 6 degrees to as much as 9 in extreme cases

ALL cars trucks etc should have the pinion angle set so that the rear joint wont ever rotate past zero.

I checked my pinion at ride height, and my pinion is pointing down in the front 1 degree. The driveshaft if pointing down in the rear 3 degrees. I have 1 1/4 " that the yoke can move in. I took the springs out and raised the rearend up as far as it will go, and still have almost the same 1 1/4" clearance. Gonna run it wed if it doesnt rain. Thanks for all the help.
