3. the hitch apparatus ties tv2trailer and SOME of them include sway dampening or sway elimination
4. pig tail transmits juice 4 battery and lights
5. chains and breakaway/brake wire are 2nd safety features IF the primary connection fails.
so AGAIN, primary goal of w/d bars is to RESTORE steering axle load.
all the other real/imaginary objectives 4 w/d bars are 2ndary and vary from rig2rig
"leveling" the truck is NOT a goal of w/d
, but may be a CONSEQUENCE on some trucks, sometimes.
1. the truck may not have been "level" unhitched, most are NOT.
2. a tad more DROP on the drive axle of REAL trucks is ok, especially when the axle RATINGs favor the rear.
like most newer mopar trucks.
my truck is 3-5 inches HIGHER at the rear unhitched and only 1-2 inches higher after CORRECT w/d bar tensioning.
but "level" isn't part of the equation, or my rigging goals except for the trailer.
rear axle is only 100 lbs higher capacity compared to the front on my truck (6000/6100),
even with the heavy diesel engine up front.
on SOME trucks this ft/r axle capacity difference is 1-4 THOUSAND lbs
and on those trucks much LESS (or none) w/d is needed...
since the steering axle may not UNload with towing (these trucks typically have a LARGE payload) .
3. REstoring steering axle loads doesn't = compressing the front springs.
w/d is NOT about 'squatting' the truck
at all corners (see the primary goal)
4. IF the headlights are pointed upwards while towing that's a CLUE to improperly adjusted w/d gear OR tires pressures...
and a minor issue... IF the front axle load has been restored correctly...
almost no truck with properly adjusted w/d gear will need the headlights adjusted...
5. LEVELING the trailer matters but is largely dictated by DROP on the shank/stinger gizmo...
one can ~ these adjustments with a measuring STICK and many readings...
but weights at the various TENSIONs on the w/d bars are the gold standard.
this thread USED 2b a sticky, and except for the lame jokes about UNDERSTANDING it or math issues...
it's a USEFUL thread on things related.
i have no idea why it isn't now a sticky,
especially considering some the CRAP threads that are stickies in other subforums...
it DOES explain some of these issues without regard to brands of ANYTHING...
maybe that's why it's no longer a sticky?
