If using a different Brand of products, Check their specifications.
In the video we installed the nuts for the hanger bolts on the outside, this was done to show you a better view of the installation and we have plently of clearance to the tires so the hanger bolt wont hit the tire even under a heavy load. Typically the nut is fastened on the inside.
Note: This video is used for guidance only, Always refer to the manufacturers installation instructions and specifications.

Johnson: what metal can you recommend to make an ecxel for a cart to carry 500 pound..and the ecxel of 3 feet long...thanks for your videos

[@shawnwallace29]

Thank you for this video. I had a leaf spring snap on me today. Nothing major happened, thank God. You're video made it easy for me to take this task on myself for $90 versus needing a tow and paying someone else to repair my work trailer for almost $500 plus being down for two days. I only missed half of a day of work and I now have the confidence to make a few other repairs. (To the peanut gallery: maybe you should try maintaining your equipment better. My utility trailer is almost 5 years old and on the road 5-6 days a week, 50-100 miles per day. While I did have rust, I didn't bust my knuckles or have to cuss or become a specialized mechanic. This video was intended for someone like myself, as an informative and teaching TUTORIAL.) THANK YOU TO THE CREATOR!

[@dcrican762]

SUPER EASY WHEN YOU ARE REPLACING NEW ONES WITH NEW ONES. NOTHING RUSTED

Yea I was thinking the Same

[@albrownmd]

Use an impact wrench to get them loose. And spray with wd40 a day before

[@jessecox4445]

Just cut the u bolts and replace

Glad you enjoyed it

[@StationaryNomad361]

Thank you man. I’m building a barbecue pit on a trailer and having to build the trailer from scratch. Nice to see how the process looks

[@ttowen02271]

Right I had to cut mine lol

[@johnsontrailerparts]

No problem 👍

[@kayagraegracelaneyfalkenma8497]

This shizZt awesome Is like I just went to work an entire practice session of hrs time , Now to begin my leafspring job tomorrow w experience like eye 👁 Done ✔️ did 👍 Thanks

[@jeffvalley67]

Really good video, thanks! As I was putting the new springs on and tightening them, I wondered if I should really tighten them. If I did, the shackles wouldn't move and this video confirmed to not over-tighten. I have a 3500 pound trailer and broke a spring while driving, what a nightmare! The new springs I got are 2000 pounds each, 4000 pound total, so I think I'll feel a bit better. I was not overloading the trailer, no idea what happened but it was not fun. Thanks!

[@johnsontrailerparts]

Your welcome, let us know if there is any other how to videos you would like to see.

[@ericvilla6286]

You're right sir! The bolts go on snug and not torqued. If the spring had a rubber bushing instead of a plastic sleeve, then you would apply a specific torque value to the bolt/nut.

[@EmMa-es7fc]

Thank you.

[@relationshipsgrowth]

nice one

[@jimtatsch3544]

I notice there is a hole in the center (in addition to the 4 holes 9n the cornets) of the spring attachment plate. Do i remove the bolt holding the leafs together and pass it through said center hole?

[@slabexpress3837]

The Kid in the video put the bolts on the hanger Backwards with the threads facing the tires. This can cause the the threads to dig into the tires very unsafe!!

[@GOASTWRITTER]

Do you need the shackles? Because mine doesn’t have them. And if I need them do they go on the front or back of the trailer?

[@bakervinci163]

Front one first. Makes sense

[@brownrecluse3772]

Great video! Is the purpose to give it more ground clearance?

[@tznutz4824]

Lol! No, the purpose of it is to show you what it would look like put together new. Most if not all these DIY videos don’t even explain the functionality of what they are replacing. 🤦‍♂️

[@yourhucklebearer9451]

Flip the axle for more GC.. Dat.... Dats WHUT I THINK..

[@eduard7811]

Hola que medida tiene los muelles , largo y ancho , y cuánto peso soportan

[@hectorrendon5313]

How do you do a c leaf?

[@Tsiri09]

I'm brand new to trailers, so this is gonna sound like a stupid question. the bracket that's attached to the trailer is only held on by a weld? There are no bolts for added strength?

[@nicolathonathan770]

Yes, it’s weld on their. And weld joint is a lot stronger than bolted joint.

[@pdlegend6829]

This is a nice video, however, the real job is to do it on a trailer that is completely rusted out with rounded off bolt heads you can't get. Anyone can do it with brand new parts!

[@ilovebrooke44]

Haha haha I just experienced this comment today

[@gschady]

what if the frame is painted red .. how would you do it if the frame was red .. WOW

[@pdlegend6829]

@@gschady it's not possible to do at all if it's red

[@bowl830]

i know right!!! wasn't realistic without the tool throwing and busted knuckle cussing .

[@christianclark347]

Kinda easier then. You just skip the wrenches and go straight to the cutting wheel.

[@taptap17]

On my single axle trailer I just have the leaf springs going to the brackets am I supposed to have one end with shackles on it

[@johnsontrailerparts]

Typically you want the shackle brackets on the rear of springs. This allow more flex in springs

[@rotfan77]

How much torque did you put on the bolts on the leaf springs? I only saw the torque on the U bolts, unless I missed it? Thanks

[@johnsontrailerparts]

on the suspension bolts you do not torque down, Behind the head of the bolt it has splines to lock the bolt in and keeps it from rotating. The nuts are lock nuts and you would tighten them down to leave about a business cards width in-between hanger and spring. This small gap allow the suspension to move freely. If you torque them down tight this would bind the suspension up.

[@maryhinge5003]

Hi there, where abouts did you position the jack to lift the trailer and do the shackle with the axle still attached?

[@johnsontrailerparts]

You want to make sure trailer frame is held up with jack stands, then using jack to support axle as you replace the shackles.

[@pacificformula]

I’m trying to replace the hangers on my boat trailer but they sold me different size hangers for the front and rear, is that correct?

[@michaeldmorrison]

Yes, you can kinda see in the video, the front brackets the entire leaf spring fits into, the rear brackets are about the same width as the leaf spring so the shackle straps will line up correctly.

[@richardsimon5945]

Great video, but I wouldn't recommend wearing slippers to do this type of work.

[@user-yg4zo8ex3i]

Can I replace just the centre bolt in the spring

[@johnsontrailerparts]

Yes, if your asking about to bolt that holds spring pack together. Just make sure to use proper bolt length for your spring pack. Typically if that bolt is rusted off. I would recommend replacing the springs.

[@nathanurick8320]

You should have replaced the plastic bushings with brass

[@cocooffroad651]

Does the shackle lift the trailer?

[@gschady]

inflate the tires with Helium to raise the height

[@jackadamz3]

[@charlesmiller3134]

Plastic bushings?

[@johnsontrailerparts]

They are a teflon bushing

[@floridacoder]

My leaf springs snapped, and I'm going to replace. I have a 5000lb axel and 27 inch eye to eye - and it didn't use a shackle. I couldn't find 5000lb at 27 inches, just at 25 1/4". So I'm 1 3/4 inch shy. My plan is to simply use a shackle to make up the difference. But I'm starting off at an angle, not 90 degrees. The higher the rise, the shallower the angle. And inverse that for a lower rise. I think it's a small enough gap that I don't anticipate any problems in the wheel well. What should my strategy be here? Higher rise and lower angle, lower rise and steeper angle, or keep searching and order exact fitting springs?

[@adamavelar2691]

That's what i have. But thought all trailer springs were 25 1/4

[@hitmenext1182]

but how do you do the other side?

[@gschady]

find a left-handed friend to hold the tools in the opposite hand or have a woman do it .. everything they do is backwards

[@dmc31405]

Good video. The music is annoying, Had to mute it before I lost my mind.

[@superwag634]

You really should put washers under nuts. And shifter? Far out 🤷‍♂️ 😂

[@johnsontrailerparts]

The hanger kit hardware do not require washers as the bolts are splined to keep them locked into position and the nuts are lock nuts. When tightening down the suspension hanger bolts they are not torqued down as you need to allow movement for suspension so it does not bind.

[@geyser3445]

You are allowed to talk.

[@thomasbullivant7717]

1st and most importantly is safety.learned that in junior high shop is always wear safety glasses.none of em in the video is wearing em.BAD example.

[@grantdevenney7078]

Also should not be wearing open toed slip on shoes! Break a to real quick that way.

[@gschady]

Crazy Russian Hacker is that you? ".. Safety is #! priority!"

[@slappy2825]

I don't sit with my legs under the trailer while its jacked either. Its a minor point maybe, but if the jack or stands give way for any unexpected reason, I don't want my legs anywhere under the trailer.

[@CazaYCocina]

Excellent video !!
