PSC Hydraulic assist chatter

tkettle said:

I am running a Currie rock jock d60 front with the PSC Hydraulic assist. I have RK drag link and Currie tie rod. When stopped or at slow speeds, I get a tremendous chatter from metal to metal "rubbing" together when turning the wheels left...? The tie rod has a LOT of roll which allows the PSC cylinder to fall onto it, and at times, the bolt on the cylinder will run along the bottom of the drag link. Curious if anyone out there has had any experience with this or might be able to recommend a simple fix...?

i didn't think the Currie tie rods were prone to rolling, did you install the washer and foam looking piece? can you take a pic?

Struggling to picture how your cylinder can rub against the drag link without pics. For tie rod roll, you can "clock" the tie rod ends in opposite directions so each is bottomed out against the knuckles where it cant rotate in either direction, according to Synergy ( I assume this applies to all JK tie rods). Either way, if the cylinder isn't parallel to the tie rod the torque on the tie rod will wear our your rod ends in short order.

yeah, those aren't Currie ends. They do sell the boot to keep the flop under control, should fit D60 tie rod ends.

I guess just make sure it is a D60, the stabilizing boots are expensive:

I have the synergy tie rod and 'clocking' does not work, when I called them about it they had just released their misalignment spacers to cure this issue. my PSC handles better since installing the misalignment spacer.

I am also a little concerned that if I head this route that I will lose articulation in the front end... Does anyone know if it will be significantly impacted if I tighten up the tie rod?

I am running a 5.5" RK mid arm lift with 40" tires... View attachment 186837

you won't lose enough articulation, if any, to even notice.

I haven't noticed any difference in articulation, it made my psc ram operate smoother and steering doesn't bind anymore

What setup are you running? What front axle too?

I have a Clayton 3.5" lift all control arms, last year I swapped out the coils for EVO 4" plush rides and King 2.5 shocks to make room for the 37's.

I got hit in the front and the insurance agreed to let me upgrade if I paid the difference so I had a Dynatrac PR44 installed using all my Rubi D44 parts that weren't damaged reused.

When the shop that did the axle swap, they also replaced the tie rod/drag link/track bar with Synergy, they also installed the PSC assist.

I had all kinds of binding issues with the PSC and after too many trips back to the install shop and them telling me it was "normal, I'd get used to it" I decided I would educate myself on the PSC system. I found out they made a few install errors and also the Synergy tie rod was flopping and hitting the drag link as well. I tried "clocking" the tie rod with no success. I called Synergy and found out they knew this was an issue and had developed the spacers. The spacers took care of the flop and hitting the drag link issue but I still don't like how noisy the Heim joint is on the track bar (having to tighten it regularly) and the drag link still has too much flop I don't feel I'm getting any benefit from it other than noise.

I rambled lol but hope it helps

Very good info Jeeeep, thank you for your help! A local off road shop recommended "the cure" from ruff stuff, but on the pictures is looks like it is on the drag link connection to the tie rod, which mine does not do... I hope I can get the Synergy ends and misalignment spacers to help this issue... Thanks again for your help!
