I put trac bars on my truck. They go from bottom of axel to inbeteeen front and rear door. I have noticed though when I make a sharp turn underacceleration I get a vibration. I have taken the trac bars off and then the vibration is gone. Is this cause from the rear end not being able to flex forward and backwards now that its like lolling the rear end up as if it had a spool??? I just want to know if anyone else had this happen and if there is a fix/ or if it is possibly hurting anything. Also the reason I put them on was for pulling and for towing. I used to get a vibration at take off when pulling and now that I have trac bars that went away but now have the vibration when turning under power. Thanks in advance for any info
maybe since the traction bars are basically solid mounted to the axle and the frame, its causing the axle to rotate up or down thus causing the pinion to point higher/lower then usual. which would cause driveline vibration.
i think you kinda mentioned that though.
anyway, thats what i suspect; is the traction bars are causing the axle to roll the pinion up or down a little causing the driveshaft to vibrate.
The axle does not travel in an arc. If you use rigid connections for the traction bar ends, opposing forces are created and need to be discipated somehow.
BTW, the trac bar is used to control lateral movement. Not the same component.
My thoughts exactly....sounds like he made them...I wonder what materials he used, length of bars, did he over "pre load', what mounts he used, final pinion angle, etc,etc,etc,etc,etc
built some trac bars - PowerStrokeNation : Ford Powerstroke Diesel Forum this has all the pics I got . Just to clarify I used him joints and used sch40 pipe. Welded adjusting nuts on end of pipe then threaded hiem joint into those. Then made a bracket that I welded to the bottom side of the axel. Then mad brackets that bolted to the frame for the other end of the bars. This vibration like I said is only under acceleration through tight turns. What I am leading to believe that since my rear axel is much more " rigid" now the limited slip is pretty much staying locked in through the turns. I was going to putting a bottle of limited slip additive in but wanted to know first if anyone else has had this happen. Sorry for the confusion hopefully this and the pics clear things up. Thanks again
your LS was going to Be in chatter situation with or without the bars ,, it does not twist /articulate enough to effect that with bars ,, but the bars mounted like yours will transmit the chatter of a bound u-joint or LS clutch chatter
Why would it then not make any noise when the bars are removed.it doesn't feel like a u joint. But I will check them. And when u say preload.......explain a little please
My excursion chatters the same as you descrbe but I have no bars. Its my LS and it only does it once the diff has warmed up. I bet like said above with the bars, you can hear and feel it more. I didnt look at the pics but if you bolted the frame brackets on you could try putting a thick piece of rubber between to isolate or put bushings on instead of heims.
Did you ever figure this out. I just installed some and notice mine doing the same thing. I instantly thought it was the limited slip not slipping enough.
I was thinking the same thing. Really good for checking what the pinion angle is doing.
