Advocate I
Anti-Sway Bars - Continued
The WJ claim to fame is the factory ride quality and off road flex. The factory did a great job of balancing on and off road (with an unusual leaning to favoring off road flex). My WJ was purchased with a 2 1/2 inch budget boost and the textbook 1" rear sway bar installed. This is a very common setup.
Since purchase I have completed the lift 'package" with correct length front disconnects, correct length rear end links, bumpstop extensions, correct length shocks, and an adjustable track bar. Also throw in the washer fluid bottle relocation and fog light elimination for additional tire clearance in the front. The suspension system is now working a lot better than when I purchased the vehicle, but there is still a bit of imbalance that presents in a few driving conditions.
Performance Observations:
Paved road manners- all around pretty decent loaded or unloaded.
Gravel/dirt roads- Understeer, severe understeer braking or accelerating on a curve.
Trail- All around pretty decent with full load out, a little stiff in the rear when day running with no load.
Front bar disconnected- awesome flex in the front, rear follows terrain more than flexing. Great over mild and moderate chop, unbalanced in very uneven surfaces. The front just flexes incredibly well and the back is adequate, but leaves a lot on the table.
Of all the parts in the suspension, Anti-Sway bars are a great tuning tool in dialing in the suspension to what you want out of it. To address the imbalance and free up the rear axle flex a bit, I swapped the rear bar with a junkyard sourced 9/16" sway bar with predictable results
Performance Observations:
Paved road manners- all around comfortable grocery getter and highway cruiser. So much smoother on the pot holed country roads. But It wallows a bit at speed and on windy roads, it will not be happy with a full load out.
Gravel/dirt roads- understeer has disappeared. Very compliant and more predictable on trail marbles or washboard with a little added speed.
Trail- TBD, but the ramp test shows improved flex. (EDIT: See post below)
Front bar disconnected- ramp test predicts a much more neutral front to back balance. The rear does not influence body position nearly as much, so the flex "load" is shared front to back much better.
Almost there, but not quite! Understeer is mostly gone, ride is smoother on chop and around town, flex is much more neutral. But full load out is gonna result in a wallowing pig. Time to dig a little deeper.
A little internet searching showed the WJ had 2 different front sway bars. A 1-3/16 " hollow (99-late 03) and a 1-1/4 solid (late 03 -04). The solid bar is stronger. My WJ has the weaker hollow front bar, and likely the 1" rear bar would be a better balance if I added the stronger solid front sway bar. But the solid front with a 1" rear bar would be on the stiff side of what I want, especially with the front disconnected. I'll stay with the hollow front bar.
So the 1" rear is a little tight, the 9/16 bar a little loose. I am on the hunt for a 3/4 inch rear bar. I swore I found one yesterday, but now all I can find is a 7/8 inch Hellwig. So not sure if the ideal rear bar exists. I'll cruise around with the 9/16" and enjoy the smooth ride, and switch to the 1" when I am on a full load out high mile adventure (like central Oregon next month...….). If I happen to run into a 3/4 inch bar between then and now, I'll pull the trigger right when I see it!
Hmm, the new Flex Connect front end links mated to an 04 solid front bar may be a perfect front system (head slap)...…….. To Be Continued
