Can you weld a stub axle?

Tack weld through the plug weld holes to secure the back end of the stub axle. Set your welder up so that you can lay a good hot penetrating weld (practice on some scrap steel) and fully weld around the stub axle and axle tube. Fill the plug weld holes up until the weld is flush with the top of the axle tube.

Can you weld trailer axles?

WARNING Welding an axle requires that you have the proper equipment and have the skill to apply a proper weld. If you are not comfortable with your welding capabilities, have a qualified welder assemble you axle. 1. Determine the axle capacity required for your trailer.

What kind of steel are trailer spindles made of?

Spindle steel varies from low grade mild steel to a higher grade medium tensile steel like AISI 1045 and come in both solid round & square. High tensile steels are not ideal for spindles as they do not have the flexibility to handle the stresses placed on a trailer.

How does a stub axle work?

A stub axle or stud axle is either one of two front axles in a rear wheel drive vehicle, or one of the two rear axles in a front wheel drive vehicle. In a rear wheel drive vehicle this axle is capable of angular movement about the kingpin for steering the vehicle.

Can I weld a new spindle on trailer axle?

There are very few bolt-on spindles available; in fact, most spindles are welded to the axle tube. Replacing a spindle requires breaking the existing weld and then welding the new spindle in place.

Can you extend trailer axles?

you can “only” widen an axle if it is a straight axle. Some axles are cambered, the factory puts a bow in them for loading purpose’s. Straight axles are no problem to widen as mentioned. To see if you have a cambered one just stand behind your trailer and look at the axle, you will be able to tell.

What are trailer axle spindles made of?

Description. This round trailer axle spindle is made from solid steel and carries a 1,250 pound rating. The bearing surfaces are 1″ diameter and the mounting surface is 1¼” diameter. Includes nut,washer and cotter pin.

What material are spindles made of?

Most commonly used materials are high-carbon chromium bearing steel (SUJ2) and martensite stainless steel (SUS440C or equivalent).

What is a flange on a trailer?

A trailer flange is used to adapt a trailer core to a rewind spindle. Once the core is seated on the flange, the film can be wound onto a reel.

What’s the best way to weld a stub axle?

Tack weld through the plug weld holes to secure the back end of the stub axle. Set your welder up so that you can lay a good hot penetrating weld (practice on some scrap steel) and fully weld around the spindle and axle tube. Fill the plug weld holes up until the weld is flush with the top of the axle tube.

How do you Weld a straight beam axle?

Place the welding earth clamp onto the back end of the stub axle (do not earth on bearing or seal mounting surfaces) and run a 5-10mm wide weld fillet around the stub axle where marked. Once welded, eye ball the welds against the axle tube to see if the weld has sufficient height to be machined.

How big is a round stub axle for a trailer?

Round stub axles are commonly welded into square hollow section (SHS) and 2″ x 2″ x 1/4″ are suitable. Finding a suitable axle material for 2 1/4″ round and square axles is a bit more difficult and most people use this size stub axle in a stepped/overlay setup on top of 2 1/2″ x 2 1/2″ x 1/4″ SHS or heavier.

Are there any problems with welded axle tubing?

One of the problems with using ERW/welded pipe as axle tubing is the seam weld internally running the length of the pipe. You can work around this if the seam is of a consistent depth or offset from the centerline of the section (SHS only), but the best thing is to get rid of it.
