Anyone's Nismo torsion bars settling a bit?

i have noticed what looks like the front of my truck being a bit lower than it was before ECXC last weekend. i was wondering if torsion bars settle a bit, or have they already begun to sag? i am hoping for the former and not the later. i am going to have to reindex one side of them this weekend in order to adjust them up anymore anyhow. (i indexed one side incorrectly when installing them)

anyone else seeing this. i am wonering if i did something wrong when i installed them. i guess i will know more this weekend.

Damn that's scary. Did you get a measurement when you finished the install? If so, let us know what the difference is. I think that there's a good chance that they are just drooping...like you said they may have settled a little. NisMos are supposed to be high performance. They use them for racing and stuff, I sure hope they aren't prone to bending. :eek:

getting nervous here. they've settled maybe .5 or more inches. god i hope that is within spec. i cranked them back up last night, but probably need to crank some more.

what scares me the most is since i had so many problems with the install, and took the bar in and out so many times, i cannot remember whether the letter are int he back anchor as they are supposed to or in teh front ones. dammit dammit son of a bitch!!!

if anyone with an ARB and winch installed with these can tell me if they are having the same problems or not and put my mind at ease, that would be nice. otherwise, i think i am going to pull the bars to make sure that i have them in there correctly. if i don't, then i am afraid i am going to have to order a new set as the ones i have will be shot from being turned the wrong direction. <sigh> god i HATE torsion bars!!!!!! i feel like such a moron.

Hello? Anyone?
I thought I'd increase this thread activity a bit to help in some small way in getting a response for Synchro.
Actually, I'm planning on installing these torsion bars, too, so I have a small personal interest here as well...:D

Synchro, now that you mention your concern over having the torsion bars oriented correctly, I thought I'd point out a slight ambiguity in Schlud's install procedure; here's a quote from the procedure:
"Each end will be stamped with a L and an R denoting which side the bar should be installed on. Right and Left are relative to FACING THE FRONT OF THE VEHICLE [bold mine]. On the Nissan Motorsports bars the stamps are on the front of each bar (so the R should be installed on the passenger side with the stamp on the front wheel side of the bar."

If "facing the front of the vehicle" means standing outside of and in front of the car, then the RIGHT side is the driver side; however, Schlud mentions that the R-stamped t-bar goes in the passenger side.
If "facing the front of the vehicle" means from sitting inside the car, then there is no ambiguity. I kind of assumed that literature that comes with the t-bars would clear this up but I'm not sure as I haven't received mine yet. Well, just thought I'd bring this up in case I'm not the only one wondering & I hope this post doesn't divert any attention from Synchro's crisis.
Good luck Synchro & hopefully someone can shed some light here.

I'll have to dig up the instructions that came with the bars to double check, but as I remember it, the right bar goes on the passenger side.

I hate when auto parts are labled right and left...is it so hard to say passenger and drivers side? I know this would be confusing with an item used on right hand drive models as well but these aren't. From any part i have had that says right or left, left meant the drivers side.

Kirk, relax...
I am sure we put those T-bars in right. At worst, your rear drivers side hanger is a little dented. But I am sure we put the right bars in the right way. We checked and double checked.

Some settling has to be natural. I bet you have to adjust at least one more time before all is done.

I just got my NisMo t-bars today & opened 'em up for inspection.
The one stamped with the letter "L" also has 3 letter "Rs" stamped on top of each other with different orientations (sideways & upside down) such that it looks like a mess until you look closer & you can see that it's 3 superimposed letter "Rs". WTF? did someone get happy with the (wrong) stamp machine or whatever they use to mark it?
I'm almost sure this is a case of QC doing its job but I'm also still a bit nervous about it.
Also, both t-bars are stamped with "1447" and "1000". Does anyone recall if this is correct? (i.e., should the left and right t-bars have *slightly* different digits stamped on them?).
Well, I'm gonna print Schlud's how-to and scope underneath my truck & get familiar with it all so that I can hopefully get the job done tomorrow or wednesday evening....
Thanks.

I haven't had any problems at all since installing mine Kirk. I'm quite sure you won't have to buy a new set, that would be nuts.

if you ship the parts to australia then it would be different no? that's probably why.

Damn Synchro, I guess we should file that under "expressions to indicate that the install isn't going as well as planned".

Seriously, I hope things workout okay for you.


It's times like these I need a little quiet "meditation"

:bonghitte

yeah me too. i guess i will find out on my way down to the plant tour and tellico on thursday. :rolleyes: <sigh>

Okay well my t-bars have sagged a bit since installing them (between 1/2 and 1 inch) - I'm going to adjust them a little more this weekend. Just updating ...

since adjusting mine last time after noticing them sag, mine have not moved. even after abusing them at Tellico. so all is good for me too.

Not that anyone cares, but my torsion bars DID NOT sag at all ... the air pressure in my front tires was WAY down ... like down to 20 - 22 psi. So I aired back up and bing, everything is back to normal. Duh.

Add me to the list.

I noticed mine had settled a bit last week. I adjusted them up about 1/2" and everything is fine again.

I thought that in that measurement exchange w/Ian on XOC a couple weeks ago you mentioned the space between the bumpstop and upper A-arm was ~1" which might have indicated a t-bar sag. I have almost 1/2" of spacing here & I thought my t-bar lift was only 3/4-1".

I may not be reading this correctly, but the space between my upper A-arm and the bump stop right under it is about 3/4" which is what it has been since I installed the torsion bars ... Ian on the other hand says he has about 1" in that space. But he hasn't answered 90% of my other questions involving measurements ... of course, then again no one else has either so ... :o

Yes, you're reading it correctly. Funny, my t-bar lift can't be that much 'cause my 31x10.5's rub the Canadian mud flaps (I've shaved them with a knife to aid clearance, too) when I back out of the driveway & turn wheels simultaneously but I don't have too much space between bump stop & upper A-arm. Another funny thing: driver's side camber can be adjusted to dead center of spec (range is .1-1.1 with .6 the target) but passenger side can only be adjusted to about .2; but, all my measurements show that the passenger side t-bar is cranked LESS than the driver's side--that is, most passenger side measurements are about 1/16-1/8" shorter than driver's side. The only thing I can think of is we're seeing car to car and intra-car manufacturing tolerances rearing they'r ugly heads. I took some measurements but I've been hesitant to post 'cause they're on the driveway w/31x10.5" tires so the relevancy is not huge but I'll try to post tonight. Actually, I'll re-measure & post 'cause I recently had my tires rotated & the tread thickness difference was pretty big.

I just installed the sway away torsion bars this weekend. I also found that the passenger side adjusting bolt required fewer turns than the drivers side adjusting bolt. As it stands now the drivers side was turned 17 full turns and the passenger side was turned 15 full turns. I get 12" on both sides from the ground to the frame, 17" from the hub to the lower wheel well, and 1" between the A arm and bump stop. I am still running stock AT's with 35 psi up front and 33 psi in the back. I also noticed when I took the tires off that my passenger side tire has much more wear on the outer edge of the tread and the truck has always pulled slightly to the passenger side. Any feedback on the ride height? To high or push it more?

if the tire has much more wear on the outside than you definitely have an alignment problem that needs to be looked at before it gets really serious. as for the height and turns issue, this could be as simple as you having the bars indexed differently. the number of turns would depend on if you had exactly the same angle of the rear anchors when you reinstalled them. i wouldn't worry about that too much, it is more that the 2 sides are even to the frame that is the area you want to look at. if they are equal you are fine.
