Thuren Track Bar. How to center axle?
I installed it yesterday. I set it at 39" and it was still a bit to the driver's side. So i adjusted to 39 1/8", center to center, and it looks about perfect now. Thanks for the info guys.
On a side note, I had to buy new hardware to mount it as the bolts that were on the factory track bar were too large to go through the Thuren track bar (i think they were 5/8" bolts). I got some grade 8 16mm bolts, lock washers, and nuts and used them to install the Thuren track bar. Has anyone else encountered this? I am wondering if it is an '08-specific occurance due to the "revised" track bar on the '08s. If so, Im going to contact Don so he can at least notify any future buyers that have '08 trucks.

Thanks for the insight. I didn't hear any sounds coming from the front end today but i wasn't really listening for anything. If i hear anything though, i will get under there and see if i can torque the bolts down a bit further.
Its some kind of Acetal bushing btw. Now I recall Don having me check the bolts on the track bar (I think it was the track bar) when I ordered mine. Man, a year goes by and it all goes into the bit bucket.
I guess it doesn't matter now because you worked the issue but I would like to know now if thats the case.
What are you going to do, call Thuren?

UPDATE: I got ahold of Don last week and let him know about the size difference. He said that he must have shipped my track bar right as he was investigating the changes. Apparently, Dodge made a switch in the 2007 model year from 14mm bolts to 16mm bolts for the OEM track bar. Don said he even saw a couple at his dealership with a 14mm bolt on one side, a 16mm bolt on the other. Mine (2008 year model) had 16mm bolts on both sides. Go figure, another brilliant move by Chrysler engineers...
So, Don sent me a replacement sleeve for the bushing and replacement heim joint spacers that fit my OEM 16mm bolts. I installed them today. There was no gouging of my factory holes for having 14mm bolts in there for the past 5000 miles and everything looked good to go, but Don and I agreed that it was better to be safe than sorry. That speaks alot for the guys customer service.
Anyway, just a heads up for any future track bar buyers. If you've got a 2007 model year pickup, you might want to get under there ahead of time and figure out what size bolts you have. If you have an '08, you've likely got 16mm bolts and not 14mm bolts like the 03-06's do.
Also, after installing previously at 39 1/8" I noticed the more I looked at the truck that the axle was still slightly off center. So, while I had it out to replace the sleeves/spacers, i spun the heim joint one full revolution longer. I didn't bother to measure it again before reinstalling but, looking at it after installation, it looks like the axle is dead on. I checked for clearance and there appears to be ample clearance in any way the suspension can articulate so I don't see any problem with 1 turn over 39 1/8" (best guess is it is 39 1/4" or so as it seemed one turn = ~1/8" length). If anything adverse happens in the future with regards to this length, i will post it here for reference sake.

Yes, Don makes track bars for the bigger lifts. Call him and he can get you set up.
BroncoHound, you will probably be fine on the length, but if the track bar is off too much, you can start bashing buckets and other stuff under your front end. Like I said earlier, I have a 3" lift and my track bar is set at 39 1/16", straight from Don's mouth.

If you call or email him tomorrow, and place an order, you will have it by the time your lift kit will be on. That is, if you havent ordered your kit yet.
Mine took about 2 1/2 weeks to get built and shipped. However, this was right about the time CA had those wild fires a few months ago, and the fires came within 200 yards of Don's shop, so he was forced by his better half to evacuate for a couple of days which delayed my shipment...
Anyone else w/ one of these track bars experience this? Could the bolts be 2 loose? Thoughts? Also heard Don is putting grease fittings on now to grease the bushings.
I've been running my Thuren track bar for 5k miles or so and at first the bushing was squeeking, now i have noticed a clunking from the front end. Assumed it was ball joints going but i was looking at my track bar the other day and it was really loose at the frame mount! It actually looks like the UHMW bushing has seperated a little and the track bar can move forward and back (relative to truck) in the horizontal and rotate slightly. Doesn't seem like there is much side 2 side movement when i have someone move the steering wheel, but i wouldn't think it should be this loose. Checked the bolts and they seem plenty tight.
