How To Mount Redline Rear Hanger # 30-20 On A Trailer- On the Redline Rear Hanger, part # 30-20, the hanger has top stamped into one of the sides of the hanger. The hanger is welded to the trailer with the side marked top, facing the outside of the trailer with the word top showing.
I am including a picture of the hangar that shows the top marking and how it is positioned on the trailer.
The Dexstar Aluminum Star Mag Trailer Wheel, # AM20305, has a zero offset. This will mean the hub mounting surface of the wheel is at the centerline of the wh

- Replacing a Spindle on an Enclosed Trailer Axle
- When replacing the spindle on your trailer with a EZ Lube Spindle 1.75 inch RD x 3 inch STUB, part # R20384EZ, you will need to cut off the existing spindle and weld a new one in place.
I would strongly recommend you take it to a qualified machine shop to have the appropriate welds done.

- The Trailer Leaf Spring, 2250 lbs. 6 Leaf, item # PR626, is sold as a replacement spring for older trailers and measures 26 inches for eye to eye, center to center.

- What Size Spindle is Needed for a M/H trailer
- The axle spindle you need to order will depend on the weight capacity of your trailer and on the type of spindle (see link) already being used, if you only need to replace one spindle.
To figure out which spindle is correct you can use the bearing part numbers, both inner and outer, and the shape and length of the spindle stub on your trailer. The bearing numbers will let you cross reference the correct spindle measurements for your hub. The axle stub shape and length will allow you to use th

- Depth of Full Size Locking Steel Flush Door Latch L3980
- I spoke with the manufacturer and they told me the depth of this door latch, product # L3980, from the recessed area to the housing area is 1 inch. The depth from top of the latch to the bottom is 1-3/4 inches. This door latch mounts in 3-3/8 inch x 4-5/8 inch hole. I am sorry, we do not have a diagram of the measurements.

- The U-bolt plates you have selected are not galvanized or coated. They are steel and would need to be painted and possibly coated with a rust preventative before installation.

- Dimensions for a Brake Mounting Flange for a 3 Round Axle
- The measurements of the Brake Mounting Flange for a 3 inch Round Axle, part # 4-44-1, are correct, in that the inner diameter of the flange is 2-3/4 inches. This is because the flange will be mounted to the spindle, not the axle. You will need to check the Outside Diameter of your spindle, as this will mount on the spindle.

- Are 3-Leaf or 4-Leaf Trailer Suspension Springs Better If they Have the Same Weight Capacity
- If the 4-leaf springs and the 3-leaf springs you are looking at have the same weight capacity and dimensions, then there is really no advantage in choosing the 4-leaf spring over the 3-leaf spring. It is recommended that you replace your leaf springs in pairs so you are using the same springs on each axle.
As long as you remain under the weight capacity of the leaf springs, the 3-leaf spring will be no more likely to break than the 4-leaf springs unless there was a manufacturing defect with

- How Should the 2-Piece Polypropylene Trailer Vent be Positioned when Installing
- On the 2-Piece Polypropylene Trailer Vent, # WHMAV2-WAVT2, I would mount it near the top front of the trailer with the vent openings pointed down or towards the rear of the trailer. Ultimately, it does not really matter. Use some self-tapping screws like # 31071 and some sealant like # L0150811 when installing the vent.

- Towing a Gooseneck Trailer with a 5th Wheel Trailer Hitch
- All of the replace inner square tube adapters that we carry like # KP84HB are 4 inches square. But there is an option none-the-less. You could replace the entire coupler, inner and outer tube, with something like # BD0289590300. Removal of the old coupler and installation of the new one is going to require a qualified professional with experience in this sort of job.
If this is not an option for you I recommend a different sort of adapter, one that fits in the truck. If your 5th wheel trailer

- How to Raise the Height of a Boat Trailer to Avoid Scraping on Inclines
- What I recommend, if the trailer has round axles, is an over-under conversion kit. For 3 inch round axles use # K71-385-00 and for 2-3/8 inch round axles use # K71-384-00. This of course will only work if the leaf springs are mounted to the bottom of the trailer now. What this kit does is allow you to put the springs on top of he axle without flipping the axle or welding.
Otherwise what you could do is use taller hangers. All of the hangers would have to be raised the same amount. So if you w

- Replacement Shackle Strap and U-Bolt for Boat Trailer Bunk Brackets
- You should be able to measure the old shackle strap and u-bolt to get the correct size replacement. Measure the center to center distance between the holes and the diameter of the holes on the shackle strap. Shackle strap # CE14103G that you have referenced measured 2-3/4 inches from hole center to hole center and the diameter of the holes is 9/16 inches. A u-bolt can probably be found easily at a local hardware store. Just take the old bolt with you to compare.

- Can Redline 2-Way Pop-Up Roof Vent 9106-2756 Be Installed On the Side of a Trailer
- The Redline 2-Way Pop-Up Vent # 9106-2756 is designed as a roof vent. However, you could put it on the side of a trailer if you wanted to. There is no specific instruction manual. You would just cut the appropriate size hole using the vent, or more specifically the garnish, as a template. Then you would use screws like # 31071 and some sealant # 0160297 to mount and seal the vent.

- boat trailer hub/spindle assembly
- Spindles get welded to axles so there really is not an easy way to replace one on the side of a highway. The best advice I could give to you would be to periodically check the condition of the bearings on your trailer and be sure to grease them regularly and you should have a pretty reliable trailer setup.
Check out the video I attached on bearing inspection for you.

- How Much Clearance Between the Top of Axle and Bottom of Trailer using Leaf Spring PRB4
- A lot depends on the hanger kit you are using. With the # PR4B spring and hanger kit # APS1 from the bottom of the trailer deck to the top of the axle should be approximately 2-3/4 inches.
If you were using hanger kit # APS4 then it would be approximately 3-1/2 inches.
You can use these measurements to determine where the top of the tire would be.

- Replacement Bearings for a Spindle that Measures 1.055 Inches

If you have access to the bearings still the best way to determine replacement parts is to get the inner and outer bearing numbers stamped into the metal of the bearings.

- Replacing a Double-Eye Leaf Spring that is 53 Inches Long on an Old Utility Trailer
- Since you want to go to much shorter springs it will require welding on new hangers just so you are aware. The PR4B spring you reference can be used with many hanger kits. The one that is going to give you the most clearance is # APS4 at 5 inches.
At this time we do not have u-bolt plates or u-bolts for a 3 inch square axle. If you already have these items and they are in good shape you could re-use them. The spring you currently have might be an automotive spring which means this might be a

- Single Slipper Spring for Tandem 6000 Pound Axles 2 Inches Wide
- To determine the appropriate replacement slipper spring you would need there are a few measurements that are crucial. In order to get these measurements the current spring cannot have a load on it.
If you have already removed the slipper spring from the trailer that works great. Or you can measure while it is on the trailer, just make sure that when you jack the trailer up you do so by the trailer frame. Also, make sure it is safe and secure before taking your measurements.

- Can a Rear Hanger that is Wider than the Trailer Frame be Still be Used
- The reason that the hanger is wider is most likely because double-eye springs are 1-3/4 inches wide. But as long as the hangers you are using are welded to the bottom of the frame as much as they possibly can be it will be fine. Welding should be performed by a qualified professional welder.

- Replacement Boat Trailer Slipper Spring for a 1998 Calkins Boat Trailer
- Based on what you have described and the measurements you have taken I do believe that slipper spring # C-4 is correct. The C-4 length is 26-1/4 inches so the mid-point length of your existing spring is on par with that. The old springs have probably stretched and worn enough to throw the exact measurement off a bit.
