Expert Answers about GMC Boat Trailer Wheels

• Do You Have a Replacement Wheel Hub For a Discontinued Harbor Freight Boat Trailer?
• Unfortunately Tim, I have no way to know for sure what size spindle you have on your discontinued Harbor Freight boat trailer. If you can provide me with the measurements off your spindle as seen in the image below I can see if we have a hub which will fit but as is most common with Harbor Freight trailers I have seen you are most likely going to need 2 new Spindles # TRU64FR and Hubs # AKIHUB-545-35-G-EZ-K.

• How To Measure For Replacement Wheels For A Boat Trailer
• Hey Gordon, If the sidewall of the tire says ST205/75R14 then you should have a 14" diameter wheel. The # AM20447 you were looking is a 15" wheel so you'd want to stick with a 14" wheel unless you have to clearance to increase the sizing. The wheel diameter is measured from bead to bead. I'd also check your wheel bolt pattern just to ensure you don't get the new wheel and find it doesn't match up to the stud pattern of the hub. I've attached a pic below showing how to measure. If you...

• Replacement Trailer Hub for Boat Trailer with Timken Bearings 07100
• Based on the bearing dimensions that you have you have a 2,000 lb trailer axle so for a replacement hub the part # AKIHUB-545-2-G-2K would work. This has a 5 lug bolt pattern. If instead you have a 4 bolt pattern you'd need the part # CE13110.

• Option to Replace 245/75R16 Trailer Tire & Wheel With 6 on 5-1/2 Bolt Pattern For Boat Trailer
• Hey Mark, thanks for the question and we do have an option for you, though not the exact LT245/75R16 M+S Radial XTX. Reason for that is those are light truck tires and not trailer tires (light truck tires will have an "LT" before the tire size and trailer tires have an "ST" before the size). That said, we have a very close option in size, with a ST235/80R16 trailer tire. These are 30.8" in diameter and 9.25" wide, so they will only add about 1/8" of height at the top of the tire and are...

• Heavy Duty Equalizer Kit With Wet Bolts and Shackles For 2018 Nitro Tandem Axle Boat Trailer
• Scott, I wish I had a way to look up the parts for your 2018 Nitro Boat trailer but unfortunately the parts breakdowns are not available to the public. I image where you are getting caught up is the 31" wheel spacing. This is a measurement you really do not have to concern yourself with. Instead you will want to measure the height and width of the bolt hole centers on your equalizer as well as the length of the shackle straps on center. I see you were looking at the Dexter Heavy-Duty Suspension...

• Recommended Replacement Galvanized Trailer Tire/Wheel Combo for a ST205/75R14 Tire
• Hey Wayne, I did some looking around and it does not look like we carry any Endurance tires in the size you're looking for. We do have the Goodyear Endurance ST205/75R15 Radial Tire # LH53FR which will work with a ST205/75R15 tire but it's also not galvanized. Instead, I'd recommend checking out the Loadstar ST205/75D14 Bias Trailer Tire with 14" Galvanized Wheel # AM3S450 which does have a galvanized wheel, will work as a direct replacement since it's the same size you're looking for,...

• Is 15' Long Zodiac Inflatable Boat Compatible With CE Smith Multi Sport Plus Boat and Kayak Trailer
• The max boat length for the CE Smith Multi Sport Plus Boat and Kayak Trailer # CE48870 is 14' so it will not work for your boat. Instead, you could use a trailer like the Malone MegaSport Kayak Trailer # MPG535 which has a maximum boat length of 20'. I'm not sure if the crossbars will work, that probably depends on your exact boat model. If you would rather have bunk boards you could add the Bunk Kit # MPG561

• What to Measure to Find the Correct Replacement Hubs on a Boat Trailer
• Oliver, to find out what replacement hubs you'll need you will need to measure your spindle where the bearings and grease seals ride, your axle capacity (which should be stamped on the axle itself) and wheel bolt pattern. Since these measurements need to be within a thousandth of an inch, you're going to need to use a caliper for the most accurate possible measurement. With this info we be able to find out what hubs your trailer uses and can point you in the right direction for a replacement...

• Recommended Trailer Hitch For A 2012 Open Range Light 297RLS
• Hey Ivan, Yes, this is a pretty common request for trailer owners that also want to haul their boat, golf cart, ATV, etc. so they add a trailer hitch and tow a second trailer. This is called triple towing and can be dangerous because you're adding more length and a second pivot point so there are laws and restrictions on triple towing that you'll want to research before attempting it. Usually the state and local municipalities you'll be driving through will need to be checked. I don't...

• Replacement Seal for Cool Hub on a 2000 Ranger Bass Boat Trailer
• Hey Mike, thanks for reaching out! I'm pretty sure your boat trailer has a 3,500 lbs axle which means you should need the Grease Seal # TMK58ZR which has a 1.719" ID and a 2.565" OD - you'll want to verify this on your end. I don't know what O-Ring sits behind your cap but if you can give me some dimensions I can see if we have one for you.

• Recommended Front Mount Trailer Hitch for a 2018 Chevrolet Silverado 1500
• Kevin, the etrailer Trailer Hitch Receiver # e98860 can not be installed in the front. You'd have to use a front mount trailer hitch like the Curt Front Mount Trailer Hitch Receiver # C31069 which is designed to be installed in the front. This hitch has a 500 lb vertical load limit, a 9,000 lb line pull capacity, and a GTW capacity of 5,000 lbs.

• What Seal Is Needed To Replace NAPA Seal 17144 And Can Work With Bearing Buddy Bearing Protectors?
• I do see the NAPA seal 17144 matches the dimensions of the Grease Seal # 58846. Since you are using a Bearing Buddy you are going to want to use one of their seal sets. The seal this size is typically in combination with a Inner Bearing # L68149 which will use the Seal Set # BB60002. This seal set is designed to be used in combination with a Bearing Buddy as it is capable of holding the pressure it creates.

• What Difference Will Using a 2" Tall Equalizer Create Versus a 1-1/2" Tall Equalizer?
• The additional 1/2" in the height of the Dexter E-Z Flex Suspension Kit # K71-652-00 will result in roughly 1/4" of additional height/fender clearance on your boat trailer. As far as the 1/4" difference in width the shackle straps take up for the slight difference in width without any real impact on the ride height.

• Determining The Correct Ball Mount For A 2018 Mercedes-Benz GLS 450 Towing A Boat Trailer
• Hi Russ, There's a few things that you'll need to check in order to get the right ball mount for your setup. First you'll want to check the coupler size of the trailer. With the boat/trailer weighing in round 5,000lbs you likely have a 2" ball coupler. From there you'll want to level the trailer and measure from the ground to the bottom of the coupler. Next you'll measure from the top of the trailer hitch receiver tube opening on your GLS to the ground. When you compare these two measurements...

• Do You Carry a 37" Long Slipper Spring With 4-Leaves For a Cox Boat Trailer?
• The 30" Slipper Spring # e89SR is our longest 4-leaf spring. I might be able to help you change out your springs with a different size that are more easily found if you can send me some images of your suspension setup with measurements from the hangers.

• How To Determine The Correct Replacement Brakes For Your RV/Boat Trailer
• Hi Isaac, When replacing trailer brakes there's a few things to check to figure out the correct replacement. The first thing I start with usually is the axle capacity. If you can find the axle tag sticker on the axle tube we can use the information on it to determine the capacity. If the axle tag is gone then you can also just measure the hub/drum assembly like I have pictured below. We can then take those measurements to find the correct brake assemblies to fit the hub/drums.

• Option For Suspension if no 2,000 lb Axle Meets Measurements
• Hi Jonathan; we do not offer an axle in the dimensions you have, so you have a couple options. One is to have an axle fabricated for you, with the other option being the 2,000 lb Timbren Axle-Less Trailer Suspension w/ Idler Hubs # A20RS545. This is an independent suspension that doesn't use an axle beam, and bolts to the frame.
