• Do Suspension Bolts Need to be Replaced when Installing the Never Fail Bushings # LC279685
  
• Since you have a 2017 Forest River Wildwood 28 DBUD the bolts used in your suspension should not need to be replaced with the part # LC281285. Unless for some reason your bolts are damaged and need to be replaced you should be good to use just the Never Fail Bushings # LC279685. Please note that Never Fail Bushings are meant to be used with standard bolts like part # TRFA73Z916DLNZ as grease will destroy them. You can use the bushings with wet bolts but only if you clean them and...

• Recommended Shackle Bolt for 2,000 lb Utility Trailer Leaf Spring Suspension System
  
• The Zinc Shackle Bolt with Locknut for Double-Eye Springs - 3" Long # TRFA73Z916DLNZ is a grade 5 bolt. Your setup as described is a standard setup for leaf spring hangers and double eye leaf springs. The # 166081 is made by the same manufacturer and is used more commonly than zinc plated for most factory applications. The cost difference comes down to supply and demand. The Dexter bolt # 007-003-01 is simply a different manufacturer that has a big name in the trailer axle market. ...

• Will Road Armor Equalizer Replace Equa Flex Equalizer # LC279687
  
• The Road Armor Shock Absorbing Equalizer Kit # LC696740 that you referenced is close enough dimensionally to the Equa-Flex equalizer # LC279687 that you have now so it will fit and work well. Bushing come with this already pre installed, for bolts you'd want the part # TRFA73Z916DLNZ but for shackles you'd need to let me know what length you have currently. I attached a link to a page that has all of the shackles we carry as well.

• Never Fail Bushing Or Shock Installation On A Tandem Axle Trailer

Even with the Never Fail Bushings and Upgraded Equalizers, you will still see an improvement in your trailers handling and stability if you add shocks. The shocks will allow for a much greater distance of suspension travel and smoother ride....

• Piecing Together an E-Z Flex Equalizer System with 3 Inch Shackle Straps
  
• Dexter Heavy Duty Suspension Upgrade Kit # K71-358-00 is exactly what you need though on a tandem axle you would need 2 sets. E-Z Flex System # K71-652-00 does not use wet bolts to hang the equalizer part. It has grease fittings on top for that so you can just use a regular bolt. So you would use # K71-654-00 for the equalizers by themselves, 2 of kit # K71-358-00, and either reuse the hanger bolts you have or use 2 of # TRFA73Z916DLNZ or a similar bolt.

• Need a 3-Leaf Slipper Spring Kit for my Boat Trailer with 2 Inch Square Axles
  
• In order to determine which 3-leaf slipper springs will fit, you will need to take a few measurements of the current springs on your boat trailer.

• Should Nuts and Bolts Be Replaced When Installing New Trailer Equalizers
  
• The bolts would have the same thread pitch as the nuts. The reason why you could only get the nut tightened a few threads is because the nuts that are used are lock nuts. It is recommended to use new hardware, nuts and bolts like the Zinc Shackle Bolt with Locknut, part # TRFA73Z916DLNZ, when replacing the equalizers. You would need to measure your old hardware to determine which replacement bolts you will need. I have linked all the suspension bolts we have available and a video...

• Recommended Replacement Suspension Parts for 18 Foot Bass Buggy Pontoon Boat Trailer
  
• If the axle isn't bent from being overloaded (wear on outside of tire tread), then you're probably okay. If it's bent, you'd want to replace it. Since you don't know the axle capacity, we can make a pretty good guess if we know the bolt pattern of the wheel/hub as well as the inner and outer wheel bearing reference numbers. Knowing the axle capacity is important, so you can choose the proper replacement parts. We offer a few standard sized 2K and 3.5K axles. To recommend a replacement,...

• What Should the Bolt Diameter be on the Center Hanger to Use with the Curved Equalizer # TREQE34
  
• If by "perch" you mean center hanger, then you would want the center hole to have a 3/4" diameter like what you find on the hanger part # 115919. This will allow you to use the Shackle Bolt # TRFA73Z916DLNZ or Wet Equalizer Bolt # 126A1 with the Curved Equalizer # TREQE34 and keep the movement at a minimum.

• Are Other Parts Required When Replacing Trailer Equalizer With Equa-Flex Cushioned Equalizers
  
• I have attached a photo of the Equa-Flex Cushioned Equalizers, part # LC279688 you can check out. The dimensions are noted on the photo. As long as your axle is within the 6,000 to 8,000-lb capacity these will work for you. While you are changing out the equalizers you may want to consider new bolts and nuts. I recommend part # TRFA73Z916DLNZ. This is a Zinc shackle bolt with a locknut.

• Gaps Between Shackle Bolt Heads and Shackles on Double-Eye Trailer Suspension
  
• 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 using washers. The spring eye does need to be able to move though so it can't be sandwiched between the shackles too tightly.

• Axle Weight Capacities Compatible with Lippert Road Armor Shock Absorbing Equalizer Kit LC696740
  
• The Lippert Road Armor Shock Absorbing Equalizer Kit # LC696740 is rated for use with two axles that each have a weight rating up to 8K so it will be fine to use with your two 5200-lb axles. The rubber cores in these equalizers will absorb much of the road shock and chucking that occurs with standard non-cushioned equalizers. If you need shackle bolts you can use # TRFA73Z916DLNZ for standard bolts/locknuts or part # 126B2 for a wet bolt that has a built-in grease zerk fitting for using...

• Is Lock Nut with Nylock Difficult to Thread Onto Bolt
  
• Nuts that have Nylock built into which is what prevents them from backing off over time. It's what makes them a "lock nut". The downside is they can be a bit difficult to thread on since it has to be super tight. You still might verify that the nuts is the correct size for the bolt and you aren't cross-threaded. If you remove the nut does the threads on the bolt looks damaged where the nut was? If so, it's not the right size or it's cross threaded.

• What Is The Purpose Of Steel band On Leaf Springs
  
• The leaf springs are normally installed with the band forward of the axle, but it is not something that has to be done that way. The steel band is called the rebound clip. Their main purpose is to help keep the main leaf from breaking on a rebound. When the weight of a vehicle or trailer is on the spring, all of the leaves work together to support the spring above them. If the wheel drops for any reason the total weight of the axle falls on the main leaf if there are no rebound clips....
