those with Weight Jacker lowers and adjustable uppers ENTER

  • Sponsors (?)


Mine bang a little too, but I also run a spool so it's hard to tell exactly what is banging on the thing! I ran the same control arm setup as you all year last year with no problems though, so I wouldn't get too worried about it. If you are really worried, switch to bushings instead of the spherical ends.

Mine are fine, did you put the supplied lube on the sides of the lower arm bushings before installing or did you lube the fittings? If you lubed the fittings after they are installed and put too much in them it is possible to mess up the bushing itself too.

The stock bushings are plyable rubber and are stationary at the mounting points, where the bolt goes thru due to the teeth in the inner metal bushing being clamped (pinched) to the chassis mounting bracket and rubber being bonded to the outer metal shell which is pressed into the stock control arm. So, this design actually has no moving parts, so to speak in the up and down movement of the arms, just the rubber flexing/twisting. The lowers you installed does have the bushings moving inside the control arm and/or the inner metal sleeve that is used for the bolt that attaches it to the chassis. That moving bushing, if moving with the arm, will cause the binding in the chassis mount and cause your noise.

The uppers with the sperical ends are probably not the cause of the noise although the factory design does induce bind at extreme suspension movement limits. I installed mine so I could correct the pinion angle after getting the ride height where I wanted it. I kept the stock bushing on the housing end of the uppers though so as to limit the amount of bind that a stiffer bushing would give in the up and down travel. The stiffer bushings will help with lateral stability but I installed a panhard bar to correct that problem.

i just got my weight jacker adjustable lower and double adjustable upper control arms with sperical rod ends installed and they sound HORRIBLE!!! they bind soooo bad...sounds like a hammer hitting the under part of the stang. anybody know what's up here?

Totally normal noise.

The hammering you hear with solid ends is why the factoy uses the soft rubber.

Its not binding its just that there is nothing to take the shock of the rapid axle movements to you hear it in the body.

well then why are people like hotrodnut and others i know not having this issue...hmmm answer me THAT! haha...well we raised the stang and looked everything over...we unbolted the lowers from the bushing end (not torque box side) and they didn't even move...they just held them selves up. so we were like, what the heck? we then tried to move them around and man were they stiff (not normal for a ball joint, which should move freely not to mention it should've swung down after unbolting it). we took the arm out and in order to move the joint we had to break it loose by putting it in a vise grip (definitely not normal). we then proceeded to the uppers after installing the factory lowers. SAME PROBLEM...it's like the ball joints just seized up on us. they wouldn't move an inch, and the driver side was worse than the passenger side. we began to jack the diff up and every pump we heard it bang and it was only coming from that driver side. we took it out and behold the same problem (seized up ball joint). the passenger was not as bad but it wasn't moving as freely as it should. so all factory arms are back in and know noise ofcourse. We sent them back to GMS and they are supposed to be sending a new set....we bought through a company called Mojo Motorsports (an ebay middle man for GMS) and they SUCK!! worst customer service EVER! I found out through GMS that they have been under investigation by GMS...so they were more than willing to replace everything (but Mojo would not). As far as "supplied lube", nothing like that was included...not even good packaging (the box was falling apart). It is obvious to me now that the arms we were sold were compromised by this company somehow. SOOOO anyways, i'll post up once we get the new ones in and let ya'll know how it goes. GMS has AWESOME customer service btw, welll so far!

go back to stock UCA's, practically everything out there sucks, you can't really improve in functions of the upper arms

Yeah thats an intelligent answer.

Everything is better stock:rlaugh: :rlaugh: :rlaugh: :rlaugh:

I see Crapnet tech hasnt changed much.

Keep it going down the ****ter your doing a good job.

get Maximum Motorsports adjustable Lower control arms and stock or frpp uppers, your brain will thank you for it.

how would that be a better set up than the rod ends? OR are you just saying a lot less of a pain.

oh and i was talking about the noise and the binding....the noise that is associated with the rod ends is ROAD NOISE, something i am fine with...but what i was experiencing was a loud KNOCK, definitely not something ANYONE can bare hearing while they are cruising..or racing for that matter.

Then why do you come here? You should just keep your overinflated ego over on the depot.

I've had double adjustable upper UCA's before, not only did they suck on the street but they were also loud. Completely removing the UCA's and installing a T/A or Tri-Link is better than adding other UCA's which are trying to do 2 jobs at once that they can not do.
 
has anyone else experienced noises other than road noise (i.e. knocking sounds) when installing sperical rod end control arms? i already know the problem with mine, but now i'm curious as to if i should just sale these when i get the NEW ones from GMS and just go with some bushing end control arms. it has been my understanding the the ball joint should move extremely easy and freely on the rod end, not so stiff that it takes a vice grip to rotate them (and they should definitely swing down once unbolted from the spring side (not torque box) instead of holding them selves in place.
 
im running a spherical/3 piece setup. ive kept my uppers stock and have had no nhv problem. ive actually found the combinations much quieter than stock(and much smoother).
one thing i did experience was when i got on it the other night. i did experienced some ass end wiggle while launching not as bad as before it is much improved.
