Assuming the loads are for the TT rather than for the TV:

Is the TT low in front when hitched with WD applied?
If so, you could reduce the load on the TT's front axle and increase the load on the rear axle by raising the ball mount on the shank.
That would make the front and rear axle loads closer to equal.

Raising the front of the TT also would increase the tongue weight. However, that might not be desirable.
If the TT's total weight is 9460+1370 = 10830#, the TW% currently is 12.7%.

Thank you for the replies. The weights above are for the trailer. The weights on the truck are as follows:
Without trailer: Front: 4280, Rear: 3300
With trailer: Front: 4150, Rear: 4800

Your hitch is not doing it's proper job.

NEVER, EVER, have less weight on the front wheels when the trailer is attached.

Adjust the hitch bars tighter and you will see the weight change for the better, as well as the handling will be improved.

I totally misinterpreted the numbers. Those numbers look good to me.

The trailer front axle IS overloaded. Worth fixing. And worth trying for FALR. Find the median, get the scale numbers for a numerical value from which to work in the future.

Is the trailer level when hitched with weight distribution?

It appears to me that the WDH is doing its job very well.

The TT's tongue weight probably is greater than the 1370# which, I assume, was calculated from the hitched GVW of 8950# minus the unhitched GVW of 7580#.
Due to load transfer to the TT's axles when hitched with WD applied, the TW might have been in excess of 1500#.

Depending on TV/TT dimensions, a TW of 1500# could have caused around 600# to be removed from the TV's front axle.
The scales data indicate the front axle load was returned to within 130# of the unhitched load when the TT was hitched with WD applied.
This suggests that around 470# might have been restored to the front axle by the WDH.
The calculated front axle load restoration (FALR) could have been around 78%.

Ford now specifies that the FALR should be approximately 50%.
Chevrolet/GMC now specifies the FALR can be 50% for some TV/TW combinations and even 0% for others.
Equal-i-zer specifies the FALR can be as low as 50%.

Therefore, the achieved FALR of around 78% indicates the WDH was performing its job more than adequately.

It's a 6000# FAWR on an '09 2500 diesel. There is room to nail the number if for no other reason that future loads may need more. Be able to dial it up or dial it down. Get it dead on for the proper start. Work the TV tire pressure numbers according to door placard. There will be a percentage after some experimentation that is just right.

Too much pressure or too much tension. No way to find it without trying.

New question.

Hi, I have a new tow vehicle and need to know which shank to use for a late model F-150. Mine is a 2014 4X4 145" wheel base. Anyone here towing with a late model F-150?

Hi, the receiver is higher on the F-150; Due to scraping, I cut the last hole off of the one on the Lincoln.

Hi, I used a pneumatic cut-off tool; It still took a long time to do. [I took my stuff to the dealership so I could use their air. My home compressor kept running out of breath] The receiver on my F-150 is about 4"s higher than the Lincoln, so even if I didn't cut the last hole off, the shank wouldn't work.

L-bracket adjustment

I don't see how to adjust my L brackets any higher. I'm thinking maybe the link plates can be reversed to raise the L bracket.

The outer link plate has a welded box on it and the L bracket slides up. In the picture you can see that the L bracket is as high as it will go, but the trailer and SUV aren't quite level.

I'd like to raise the hitch ball so I have more clearance to avoid ground strikes and so I can unhitch easier. If I raise the ball that reduces the pressure on the spring arms, so the L bracket needs to be higher also

Advice would be appreciated.
