Troubleshooting Trailer Suspension that Shackle and Equalizer Flip Over  

Hi Adam, SumoSprings will not affect your unloaded ride height, but are designed to help support your suspension when loaded so that you maintain your factory unloaded ride height. The colors dictate the weight capacity of the spring so black ones…

If the shackles are flipping the wrong direction frequently that typically means the leaf springs are too short, the hanger spacing is too big, or the shackles are too short. Most of the time it's somebody changed leaf springs and just went…

A bearing race or cone should fit tightly enough in the hub that it needs to be driven out of the hub with a punch from the back side. If the race is spinning in the hub, either the wrong race was used or the hub bore has been damaged in some way. If…

It's okay to replace leaf springs with ones rated for more weight and pretty common to do so but keep in mind, the higher you go the rougher the ride will be. If you have a utility trailer then I'd probably opt for the higher rated 5,000 lb…

Generally the issue when shackles flip when hauling empty is that they are too short. So I recommend measuring them from center hole to center hole and assuming they are less than 3 inches, replacing them with longer ones, the 3-1/8" Shackle…

Yes, the Replacement 5-5/8" Equalizers for E-Z Flex Heavy Duty Rubber Suspension System #K71-654-00 will work for your trailer since the dimensions match with your current equalizers. These will work with axles up to 6,000lbs. I believe the kit…

When installed properly the portion of the bearing that attaches to the spindle should not spin. Only the outer portion should be spinning. It's pretty easy to overtighten a spindle nut since they don't have to be very tight so that would be…

Although they are not rated significantly higher, installing the #e57SR could result in a noticeable difference in the ride. Springs rated for your 3,500 lb axle (1,750 lb spring capacity) would be the better option. I'm not sure what you had…

From the numbers you provided it sounds like you need replacement grease seals. In my research, the grease seals I found with the GS-1719DL number have a 1.72 inside diameter and 2.565 outside diameter. The replacement double lip grease seals you…

Wheel torque specs vary based on stud diameter, wheel diameter and wheel material. The linked chart shows you commonly recommended torque specs for a range of studs and wheels. For 1/2-inch wheel studs and a 14-inch steel trailer wheel you will use a…

Yes, the temperatures you mentioned are normal. If you were getting over 200 degrees that would be a bad sign. But typically if all of the hubs are the same temperature you're good and it's only really an issue if one of the hubs is hotter…

We recommend that all trailer tires be inflated to the max psi stated on the sidewall of the tire. If the tire is under inflated, the weight capacity is lowered to an unknown amount for that tire. Although running lower air pressures can improve the…
