Email between me and Anderson Customer Service:Jim,Thank you for contacting us in regards to our Ultimate Connection Hitch and due to some flex in the bed of the truck we have changed the torque sequence on the base of the hitch to ensure it is snug when towing.Place base over gooseneck ball and pin to the gooseneck ballTighten upper bolt to 50 ft.lbs of torqueLower Trailer onto pyramid base (prior to tightening the two lower set bolts)Re-torque the top bolt to 50 ft.lbs in case any flex of the base or bed came into play.Tighten the lower two set bolts on the coupler tube to 40 ft. lbs.Thanks,Dave.On 2015-10-07 13:36, Jim Cummings wrote:Recentlly I read that Anderson revised the torque sequence on theuntimate hitch?

From their online PDF instructions...4-2. Place the pin through the lower coupler sleeve under the gooseneck ball and secure it in place with the hairpin clip. Push the entire base forward towards the cab of the truck until it will not go any further.4-3. Using a 15/16" socket wrench, tighten the top bolt of the square coupler to 50 ft-lbs of torque. This will ensure that the coupler is pulling up on the gooseneck ball and holding the ultimate connection firmly to the bed of the truck.4-4. Line up the King Pin Coupler above the Ultimate Ball and place the full weight of your trailer onto the ball. Secure the Coupler Block by using the remote latch and then locking the remote handle in place (see previous page).4-5. IMPORTANT Now RETIGHTEN the top bolt to 50 ft-lbs of torque (see step 4-3 above). This takes up any extra slack from the Ultimate base.4-6. Using a 15/16" socket wrench, tighten the two square coupler set bolts to 40 ft-lbs of torque to take out any play in the tube. DONE. You are now ready to attach your 5th wheel trailerto the base unit

This has come up previously. I tried it the last time I hooked up my 5er and it made no difference after putting the pin weight on the hitch. That is why I ask. If you have a rubber matt I could see the need to re-torque, but IMO its not needed otherwise. My pin weight is 2Klb dry so maybe some heavier pin weights may see a benefit.And this needs to be removed form 4-6: "You are now ready to attach your 5th wheel trailer to the base unit". Trailer already gets attached in 4-4...

I have a rubber mat under mine. When I asked if that was ok or a problem, Andersen basically said "That's great!" :) However, there have been a few times where I've gotten a pretty significant, startling CLUNK 10 minutes into a trip after reinstalling the hitch. I'm going to give this new installation and torque sequence a try.

Got sprayed in bed liner, my utimate has moved 1/2 while towing

How far can u turn after hooking? 1/4,1/2. full turn?? What is your pin weight?

It's odd some are having to re-torque while other like myself don't.

Bed Flex?? :h

No way :B

I haven't had to re-torque after hook up,however I let it set for a few seconds then re-torque when installing . I do have a spray-in-liner.
Might be the difference in brand of turn-over ball, I have a Curt which uses a double locking pin. Maybe the wrench some use.

reviving a sleeping thread, but just had to update ... experienced the same CLUNK with an ATV trailer behind the truck this weekend, so it is NOT an issue with the Andersen. Still investigating.

Just spitballing here but have you looked at the spare tire mount? Mine was banging one time it was the tire hitting the hitch frame underneath

Just hooked up today and was still at 50ft/lbs after attaching trailer. Couldn't turn It at all.

When I install the hitch I turn the top bolt REALLY slow and can get a lot of turns on it and it's **** snug against the bed.

You may be cranking it down to fast.

Look up axle wrap...or could be that your slip joint on the drive shaft needs lubing...either one is not a real problem.
