Is Lock Nut with Nylock Difficult to Thread Onto Bolt  

Trailer tires and wheels are not balanced before shipment as the weights could potentially fall off during shipment. Also, trailer tires and wheels, especially of this small size, do not typically need to be balanced and most tire shops…

A leaf spring like the part #e28SR has a distance of 25-1/4 inches between the spring eyes. I did some checking and the hanger kit you would want is the Single-Axle Trailer Hanger Kit #APS4. And the distance between the spring hanger centers should…

For a 9/16 inch shackle bolt such as #TRFA73Z916DLNZ you will want 65 to 95 foot pounds of torque. Provided that you are within that range you won't over-torque the nuts. A little bit of play is expected but large gaps could be taken up…

The axle U-bolt torque spec will depend on the bolt diameter- • 5/16 inch- 65 ft/lbs • 1/2 inch- 45-70 ft/lbs • 9/16 inch- 65-90 ft/lbs • 5/8 inch-100-120 ft/lbs • 3/4 inch-160 ft/lbs Shackle bolts don't typically have a specific torque…

In regards to trailer suspension kits like the Suspension Kit for Tandem-Axle Trailers part #AP233, the shackle bolt heads are indeed seating into the hangers via the knurling on the bolt. If you hold a wrench on the bolt head and tighten the nut,…

The U-Bolt Kit for Mounting 3,500-lb, Round Trailer Axles - 5-1/2" Long U-Bolts #APUBR-1 do not have a specified torque from the manufacturer. I did some research online and it appears that about 72 ft lbs would be appropriate for the 1/2 inch…

Have you tried tapping the bolt in with a hammer? Hopefully not much force would be needed. Ideally you get the splines seated all the way but then you don't have to really torque the nuts down as the bolt needs to allow the suspension to move.…

I have attached for you below some common torque values needed for a trailer suspension system but a lot of these will vary by bolt size and other factors. U-Bolts: Varies by Size - 1/2" bolts: 45 ft/lbs - 70 ft/lbs, 9/16" bolts: 65 ft/lbs…

There is no specific torque rating for shackle bolts. Basically for the middle bolt there should be enough free play in the shackles to allow them to move. Tightening the shackle bolts too much will squeeze the shackle straps against the leaf springs…

The nut on the spindle should be tightened until snug, with no side-to-side play in the hub and then backed off slightly, about maybe a 1/8 of a turn. If the spindle uses a castle nut and cotter pin or tang nut, tighten the nut finger tight until it…

For your Forest River Sandpiper 5th wheel with 6,000 lbs axles, I recommend the Roadmaster Comfort Ride Shock Absorbers for Tandem Axle Trailers item #RM-2460. This system fits tandem axle trailers with 3" diameter 5,200 lbs -7,500 lbs axles. It…

Because they are maintenance free, less expensive and easier to install than shocks, I'd definitely recommend going with the SumoSpring option. They'll work with your existing leaf spring suspension to help dampen the suspension, but will…
