Sorry it's long....wanna be thorough in explaining
need a little direction here as I'm baffled on this. This ain't my first 1Ton swap by far haha, but this one is being a bugger for some reason.
Just did this 1Ton swap in a TJ with 08 Superduty Axles, new ball joints, new wheel bearings, new factory tie rods, new radius arms with 1.25"Heim joints on frame side, Track bar with 1.25"Heim joints on both ends, Drag link is dead nuts parallel with Track bar, New 14"Coilovers just installed at same time, Caster is right at 4.2, Toe is perfect right at 1/8" in, Brand new 35s balanced checked twice....freaking death wobbles like no tomorrow if you hit a bump at speed or launch it from a stop with the Gen 5 it has, not that it matters but it does haul ass being only on 35s....
the ONLY thing left that has "play" in it is the steering box/sector shaft/pitman arm. Has A LOT OF PLAY when your anywhere but straight...I've tried adjusting it and doesn't do anything, takes up some of it but then it's super tight when straight and drove terrible...so i put it back to where it was.
Question: Is this Steering Box play my Culprit? or the Radius Arm Bushings are the only part left stock or unchanged on the axle but I'm just not convinced that they are the problem. Ford says they don't carry them cause they pretty much never sell them. Had a friend send a Ford Master Tech over to look at it and he found nothing wrong either and is assuming steering box as well at this point...he doesn't believe it's the bushings either cause he works on mostly Superduty Trucks and practically never changes them?!!?! idk, but I've been to his shop and he knows them trucks but doesn't really know anything related to these axles being under a jeep with Coilovers and Heim joint/etc etc.
Is 4.2 caster not enough? I see some say to run 6-8* but dam that's a lot. Pinion is already parallel with the ground. I'm checking Caster on top of the knuckle where Tie rod mounts (where Ford guy told me to check it)
The ride height is only equivalent to the same 4" lift it had before so it's not sitting super tall, angles on everything is pretty mild.
Customer ordered a Red Head steering box and I'm installing Hydro assist when it shows up cause he was going to do that in the near future but looks like now is the better time lol.
At this point I'm wanting to learn why it's doing this rather than just replace the steering box with hydro assist and call it good. (I'm 99.9% positive the Red Head box and hydro assist will make the wobble go away weather or not it fixes it or just masks the problem like dual stabilizers would but I'm not satisfied with that one bit. I want "to know 100%" that it's fixed and have a piece of mind that me and the customer can safely enjoy all that power it has without having fear when hitting an overpass. Going over a bridge or hard bump is about mostly when it does it but dam it lets loose at 65
