Re: THe NAC Lots-O-Post Thread

The uppers have flex joints at both ends already. The lower mount isn't 100% parallel from frame to axle so the rubber bushing isn't gonna last

Huh?

Need pictures. So they already have rubber bushings installed, but are at the wrong angle?

Cut off, reweld at correct angle, install bushings, problem solved.

I still don't see how it'll try and pull the pinion two different directions

Re: THe NAC Lots-O-Post Thread

because one upper will need to be longer than the other when you flex out. I'm not sure but I think if the uppers and lowers have the same length and offset at the axle and body end you can get away with it, need to think through this a bit more.

Take one upper off, now you have a 3 link. Replace joints as desired.

Huh?

Uppers are rk flex joint at the frame, rk tombstone flex joint on the axle. Lowers are flex at axle rubber at frame.

Axle side mounts are wider than the frame side

it will

stop being difficult. you dont need as much deflection as a radius arm, but you still need something to absorb deflection.

I'm glad we built my 3-link.

Hard to explain over the interwebz.

Basically, hold your index and middle finger out in front of you with both hands parrallel to each other making two Ys.

Rotate one wrist down while the other stays put.

Your index fingers are the UCAs, middle fingers are the LCAs.

Note how the one that goes down, the UCA would pull the pinion down while the one that stayed put wants to hold the pinion foward.

OHH.

I've noticed sometimes that my driver side front tire will climb in the air when the passenger side front tire is the only thing crawling up something.

Doesn't affect stability or anything, just funny how that works. Probably has to do with the torque of the driveline pulling that side up or something.

is this the same 99 as last week?

Re: THe NAC Lots-O-Post Thread

This past week I was thinking about picking up material to build a 3 link over the winter now that I'm actually motivated and enjoying my time working on the Jeep a few hours each night; would start with building a trans crossmember and t-case skid and work from there...

Now you guys are talking about it again and making me think I should really just buy a kit. :laugh3:

mine did that when i ran shocks that were too short for one run.

Imma run it til the bushings splode then do something about it

Nah not like that extreme. My limit strap isn't tight when it happens.

I mean like at the beginning of this video.

Re: THe NAC Lots-O-Post Thread

if either of your front tires are on the ground when you get to the top of an obstacle you're doing it wrong

tires and axles that aren't on the ground don't get stuck on things
