cutting axle "C's" and caster angle questions.

[fishEH]

Brett , tipping the t case up was recommended by tom woods in hope to bring the angle closer to 90° instead of at a positive angle / .

Mongo , with +3°of caster it drives just fine. With 0° its very much on edge , tends to follow road imperfections and does not track straight .

Well I guess I don't understand what's going on here...... between raised TC and additional radius arm axle mounts you're pretty far from a stock setup and it may difficult to ascertain what the root of your problem is at this point.

But as Kyle and Frank mentioned with your lift a DC shaft(stock or TW) should suffice without much modification.

hmmm…sounds like the housing, radius arms or frame/axle mounts are tweaked...

All of those are very possible , a bent frame seems most likley....... It had been crashed before i bought it but it doesnt look like its ever been on a jig but i can't be sure.
Fuck it back to looking for toy axles

Everything could be put back to stock geomitry , without cutting or welding with the exception of the shock towers (I threw the old ones away).

So judging by how supprised everyone else is I'm assuming frank is right.

I have stock D2 towers I'll send you for free if you want. Personally, I would drop the TC back to stock and use the stock radius arm axle mounts, toss a driveshaft with good joints in there and see what's what.

I'd follow Brett on this…

I don't want you're shock towers , but appreciate the offer.

I'll say it again (3rd time )
When I go offroad for the day , I put the axle at stock geometry (factory bolt holes) and remove my third limit strap.
Lifting of the tcase was done some time ago , and it made the situation better !
I surly can drop it back down , and will Sunday to re-think. But although were not talking much it does lessen the angle . trig doesn't lie .

I guess I'm just confused because you're acting like you're the only one with a 4" lift. Dudes with 6" lift and 6 degree arms don't eat U-joints like your truck is. Frank is right, something else is wrong with your truck. Why are you coming on here asking for answers, if every time someone suggests something to you, you shoot it down?

I have the same lift as you with 3 degree arms and haven't had to replace any u-joints, flanges, bearings, etc. You shouldn't expect too much articulation with radius arms anyways, go 3/4 link if you want anything.

Again, I know you'll be all pissy and be like, "but no, c'mon, you're wrong". But stop, because your truck is messed up, it's not our fault.

Not being pissy , just seems like people reply without reading what already has been posted , hence my regurgitation. I also confused positive and negative caster it seems backwards in my head.

I live in the land of no land rovers , especially lifted ones but I have owned three d2's, two were stock and remained that way. I've went wheeling once with another d2, and I never touched his shaft.... We even slept in the same room. So its not like I can just measure someone else's truck. And it never crossed my mind that the frame might be bent until frank pointed that out. And its been this way since 2008 , and have just lived with it for the past 6 years. Obviously something major is fucked with my truck (like the frame) since nobody else has similar issues.

I had 3" tf springs with 1" spacers on my d2 with 3°castor corrected arms in the front and drove 70 mph on 255/85/16's all day long with no issues. If you want to cut,hack and weld shit to try to fix the problem have at it but your pinion angle is not the issue. For once Zak is kind of rite. Your best bet is to build a jeep like Frank.

I am confused about the numbers. OP said he had: 3 degrees, upper joint to the rear of the lower.
Is this not the correct direction for proper castor?
Having the upper joint in front of the lower joint makes it like a shopping cart?
Easy to turn but no directional stability (twitchy) and poor steering wheel return to center.
If the OP has castor corrected arms, his only choice to correct pinion angle is to cut and weld.
This is easier than you would think, if you can cut a straight line and operate a hammer and welder.

I have 6 degrees in my drilled swivels with the upper joint rotated to the rear. Corrected my steering vagueness and twitchiness but did nothing to help with driveline vibration.

Thanks for the reply , I wish that were the case with mine . won't know till I have some time to see if my frame is bent.....
