I'm in the process of ordering a set of True Track bogie "controllers" for my front bogie, to eliminate the tendency toward rut steer (not a huge problem, but annoying enough to want to do something about it).

Then it hits me - my rig has aftermarket swaybars on both bogies. I really (REALLY!) like the stability these provide, and would really NOT want to remove them. But since the True Track device bolts onto the same place the swaybars do, I'm not sure there's room for both, or that they won't interfere with other components (mainly, the lower shock mount/bushing).

Here's a photo of my front bogie:

If you're wondering, the washer on top of the swaybar bushing has "smooshed" that blue top bushing - indicating to me that the swaybars really DO exert some force to keep the coach level in a turn).

Has anyone out there installed BOTH the True Track and swaybars on their front bogie?

Mark.

Probably pretty easy. I mixed the Tru-Track with the Reaction Arm Brake,
which uses the sway-bars as the lower brackets.
The Tru-Track brackets will sandwich between your sway-bar brackets and the
bogie. You may have to do some creative
trimming, depending on whose brackets you get, but I see no big problem.

Gary... yes, photos would be VERY helpful. FWIW, I took my photos with my phone, just sticking it behind the middle tire and pointing it in the general direction. I took a lot of photos to get a few that actually look good. Wink

All right, it required a bit of begging, but I got the pics on the
photosite. Try this:

Thanks for the photos, Gary. I'm not sure how much it will apply to what I need to do though - the True Track system I'd be ordering is the one with the Delrin thrust plates, not the needle bearings. This one: http://www.appliedgmc.com/products/full/1214.jpg

It looks like most of the modifications you had to do were related to the Reaction Arm modification. I believe my sway bar mounts, and the True Track mounts can end up "sandwiched" - I'm just not sure if the end result will be thick enough to cause any problems (mainly, by flexing enough to hit my shock mount on the frame).

No help with the issue at hand, but I am a strong proponent of the true-trackers. I have them on all 4 bogies, thanks to my Beloved PO.
