front driveshaft modifications

[mark]

has anyone ground the cv joint cage on their driveshaft to get some
more angle?can i expect extreme vibration or fast u-joint failure?the 60 im putting in has a much longer pinion and i dont think ill have to have it lenghthened.ill have some pics up soon of this dana 60 rear converted into a 60 front with 44 yokes. http://www.cs.colostate.edu/~zeimet/ubb/eek.gif http://www.cs.colostate.edu/~zeimet/ubb/eek.gif http://www.cs.colostate.edu/~zeimet/ubb/eek.gif http://www.cs.colostate.edu/~zeimet/ubb/eek.gif http://www.cs.colostate.edu/~zeimet/ubb/eek.gif
thanks

I thought about your idea... hmmm... would it work? CV's are made to operate at a given max angle and no more(I don't know why). I haven't looked at mine yet for a good visual, but would say from memory I don't think it would work. The pivot ball between each joint(I believe) would prohibit any more angle from being gained. The cups on each end that it rides in almost make contact with each other when it's rotated to it's max angle as it is. I don't see this working in my head. Remember... I haven't looked at my shaft yet... just going from memory right now, could be a good possibility.

Can't wait to see that Dana 60...or 44... maybe since you're combining the two we should rename it.... say a "MARK 104"? http://www.cs.colostate.edu/~zeimet/ubb/biggrin.gif http://www.cs.colostate.edu/~zeimet/ubb/biggrin.gif http://www.cs.colostate.edu/~zeimet/ubb/biggrin.gif http://www.cs.colostate.edu/~zeimet/ubb/biggrin.gif http://www.cs.colostate.edu/~zeimet/ubb/biggrin.gif:!!!

Sure you can relieve the front shaft at the C.V. joint. I did mine while i was waiting foe my woods custom shaft. According to them the max operating angle is 30 deg. I would stay far enough away from this angle but i was told they will work for offroading use. They also recomend there lifetime warranty on shaft that are run at such a high angle. if you are going to use thesevere angle you should have a part time kit to keep wear to a minimum. good luck

thanks fm
im gonna get a tom woods also.just how much did it cost?is it worth it in your opinion or is it basically the same as a stock dual cardan joint which has been relieved?

my shaft ran about 300.00 w/ the lifetime warranty. could of found it cheaper but the other people laughed at me when I asked about the warranty. They make a high relief CVjoint for about 20.00 more or call them they are great to talk to. They also have an awsome web page that explains all the angles and fixes I highly recommend going there.

Mark,

Did my angles this weekend on the vertical QT. Rearend was fine and the front would never woork with my off set diffs. These are the exact measurements of the vert.:
moves 4.75" down and 7.25" in to the center of the rig. FYI

Now... about this Tom Wodds Driveshaft http://www.cs.colostate.edu/~zeimet/ubb/biggrin.gif!!!

My front QT yoke angle, at a straight shot to position of the front diff yoke is 32 degrees. http://www.cs.colostate.edu/~zeimet/ubb/eek.gif http://www.cs.colostate.edu/~zeimet/ubb/eek.gif The Front diff to QT is 14 degrees. http://www.cs.colostate.edu/~zeimet/ubb/eek.gif http://www.cs.colostate.edu/~zeimet/ubb/eek.gif I would like to talk to these people (Woods) about this. I am going to look up the site ...thanks quys you're a great help to me.

thanks guys,tj-fm
i already talked to tom woods a little while back.my front angle is 30 deg exactly.he told me i had to get to 24 max somehow.he also said you could drive all day with one of his shafts at 22 deg.i was going to lower my whole driveline but then we started working on the dana 60 front.we are going to point it straight at the q-track.im hoping a good cv joint and the angle pointed straight at the case that i can make it without lowering everything.i havent had a front shaft in in 3 months now and my q track has been locked in E-DRIVE for as long!FM,is the cv joint on the tom woods just like our stock ones,with more relief?in your opinion can we save some money by grinding relief in ours and being ok for a while?or is there something very unique about your driveshaft? http://www.cs.colostate.edu/~zeimet/ubb/eek.gif http://www.cs.colostate.edu/~zeimet/ubb/eek.gif http://www.cs.colostate.edu/~zeimet/ubb/eek.gif http://www.cs.colostate.edu/~zeimet/ubb/eek.gif

hey tj did you see this?

Nice fabbing Mark!!! http://www.cs.colostate.edu/~zeimet/ubb/biggrin.gif The tackbar mount looks awesome and the laddarebars to. One thing I have to ask...the ladderbars...they look "hinged" on the framerail... is this correct? http://www.cs.colostate.edu/~zeimet/ubb/confused.gif Another question on the ladders, I do ALOT of axle tweakin' and noticed there seems to be no provisions for off-camber with the ladders (twisting side-to-side). If I'm wrong, correct me. My fear is wearing out bushings on the ladder from twisting.

(sorry for 'side-barring' here but I'll get to the driveshaft issue)

Also, I have got a plan totogether to do the shackle flip in the rear (and mods to the front of the rear spring as well) which would only take a 3-4" block!!! I'll let you know how it's coming...

Now...back to the driveshaft. You said that Tom Woods said to get down to 24 degrees max... I figure this would be full droop angle and not constant flatland wheelin' angle...right? Mine is 32 degrees on the ground and haven't even thought about measuring the droop angle yet! http://www.cs.colostate.edu/~zeimet/ubb/eek.gif The natural angle of the engine/tranny/QT is down (angled) toward the rear...to lessen the front yoke of the QT, wouldn't it be logical to RAISE the rear of the QT? I know... this would cause a steeper overall angle but would in theory lessen the angle of the front QT yoke. I might go out and check it tonight and let you know what I find out. Your Thoughts???

tj i think your right.i looked and thought the same thing.my ladderbars are on sort of shackles at the moment.the original mounts are welded in place and they didnt reach after the new rear was put in.this is only temporary and i hope to take them completely off soon.when i put the other block in the rear to level it off i couldnt even touch the gas without the rear pinion jumping all over the place.it was horrible.i didnt want to but i had to put the bars back on.they did solve the prob though.i work next to a spring shop and they said all we have to do is start stacking small leaves under the skyjackers.im going to give it a try.he never did say how much it would cost though!with all leaves the pack would probobly be 9 inches thick! http://www.cs.colostate.edu/~zeimet/ubb/eek.gif http://www.cs.colostate.edu/~zeimet/ubb/eek.gif http://www.cs.colostate.edu/~zeimet/ubb/eek.gif http://www.cs.colostate.edu/~zeimet/ubb/eek.gif http://www.cs.colostate.edu/~zeimet/ubb/eek.gif

Just my two since about the DL angles. I would think long and hard about getting to severe on the rotation of the front diffs.
That pinion bearing is slinger type fed as the gears are turning it has a small drain area in the casting. I know some small cj owners that overfill there diffs to make up the angle difference.

The front dhaft that Woods sell is not a lot different than the one you already have. I purchased all dana/spicer parts note the higher price. I relieved mine for a temporary while I waited for the new one. The one thing that I recomend is you take the joint apart while you are burring it to keep the trash out of the joints. Make sure you mark it so it goes back together in the same relationship for balance purposes.
