Hi Pat,

Thanks - I took the new truck out to my trailer today and hitched it up for the first time. It was definitely riding nose up with the 2" drop bar that I had.

With the truck/trailer parked on level ground, I then took measurements from the ground up to the belt line decal. I took a vertical measurement up between the two axles to the beltline, then did the same at the front of the trailer and noted the difference in heights - about 2 1/2 inches.

I then took dimensions along the ground between the two vertical measurements, and also the further distance to reach the hitch.

I was then able to protract the difference in heights and concluded that I needed another 4.2" drop at the hitch to get things level.

That seems to mean swapping my 2" drop for a 6" drop.

I'll call Hensley tomorrow and see what they say - if they recommend a 6" also, I'll go for that.

My truck has 17" wheels. I think some of the 2500HD's have 16" wheels. maybe that is what yours has?


Brian.

Hey Brian,

What were the distances between the 2 vertical measurements and the distance to the hitch?

We will check your math.

I'm thinking, especially with the smiley face, that you are yanking my chain!

But just in case you are not, believe me I could use a double check, so here are my numbers!!!

These measurements were taken with the trailer hooked to the truck on pretty level terrain and using a 2" drop stinger......

"A" = vertical ht. to belt line decal between the axles = 48-11/16"

"B" = vertical ht. to belt line decal at front end of belt line decal = 51'-1/8"

"C" = horiz. distance between "A" & "B" = 136-1/2"

"D" = horiz. distance from "B" to hitch = 99"


so, using similar triangles, I think the amount I need to drop at the hitch
should be:

(B-A) x (C+D)/C = (51.1-48.7) x (136.5 + 99) / 136.5 = 4.2"


So I figure that I need a 2 + 4.2 = 6.2, or 6" stinger to get a level trailer.


Go on, fill 'yer boots!

(Actually, If you think I've screwed up with my measurements, please do tell me!!)

Yup, checks out, so that confirms it probably won't be right once you receive the new bar

This assumes of coarse we live in a Euclidean world.

Hehehe,


You know, after being retired 10 years, its surprising how much the old brain cells slow down when not being challenged enough! I better get me one of those brain exercising programs!

Anyway, thanks for the double check, I'm going to call Hensley today and see if my logic makes sense to them!

My trailer came with a class 4 trailer hitch welded at the rear. I was going to use it for carrying our mtn bikes, but I am going to heed the advice of many on this forum and not use it. Instead I will put a hitch on the front of our new track as i did with the last one.

I figured that since I wasn't going to use the receiver on the back of the trailer, maybe I should just cut it off with an angle grinder. Some folk suggested I should leave it on - better it drag coming out of steep exits than the bumper.

That's ok, but it is quite low, so if I can't get my trailer dead nuts level, I'd rather have it a bit nose down than nose up - unless there are other considerations, which no doubt someone will now tell me about!

Zerts

Hi all, Just finished up my upgrade to the 1400 Lbs spring bars and share my experince. It was a cold and rainy day in Eugene, OR but it only took me a couple of hours.
Interesting taking the old ones off, more difficult than putting on the new. Seems as the zerts were improperly installed or adjusted. Screwed in too far, threads were scored by the grove in bar. The single bolt holding the bushing was quite loose. Had to back out the zerts to clear the bars.
Mind you only 5000 miles on this.
Notice the new versus old, not much left of the spring nubs and no spring to them.

I am hoping I installed the new ones correct. After bolting the bushing into place, using my finger, I felt up into the bushing while screwing in the new zert. When I felt the threads flush with the bushing I backed out .25 turn and tightened the nut.
Haveing no instructions thats the best I could do.
Yep, I greased it up good, and wouldn't you know it ran out just before I finished using the grease gun on the first bar. Have to go to the store for more.
If anyone thinks I missed something please let post.

OSO:

Check out my post #498, and you will see that one of my zerks looks just like yours.

I figured it was installed with insufficient grease since I heard a loud metal on metal grinding noise that started with the first turn leaving the dealer's lot.

Of course at the time I was too ignorant to know what was causing the noise.

Yep, pretty much the same. Guess if I had searched the thead better all my question would have be answered. I would hope now that the zerts are in far enough without been to far. I think I am safe. Thanks

Trial and error.. screw zerk just far enough so you can feel the spring plunger thru the bore.

Lost two from over 'screw'n.

Iv'e found thru TAE that if the bar doesn't drop out easily when swung out that the zerks are too tight. I gave up trying to count threads. Just stick your finger up the hole and feel for the nub, start out slow and turn it in a little at a time.

Guess I will have to play in the grease again, I can't wait.
Maybe it won't be raining.

On a positive note, if it is raining, your hands will repel the water and stay dry.

Great idea, Sean, when I get the chance to get to this task it will probably be clold, rainy and windy. I will just smear the grease all over me before I start. The antisipation is is almost overwhelming.
