Hi,
I guess you meant the steering is loose.

A 1948 Cub originally had the style of steering arms in the pic below from TM Tractor.
They are at the ends of the front axle.
They are held on with a setscrew. The tip of the setscrew is tapered, and goes in a tapered hole in the upright spindle shaft.
The tip of the setscrew and the hole can wear with use, over time, and the arm becomes loose.
This makes play in the steering.

Check to see if the arms are loose on the shafts. Loosen the locknut and tighten the setscrew if needed.
If the tip of the setscrew is worn, it could help to replace the setscrew.
The tip of the setscrew can break off also. Then it needs repair.
TM Tractor at the bottom of the page has new setscrews.

Yes that is correct for my tractor but I would like to know about the gear box the steering arms seems to be fine

Where is the slapping noise coming from?

Where is the slapping noise coming from?

It sounds like it is coming from the bell housing but can't tell for sure

[Don McCombs]

Was it running normally, in second gear, before the tire change? Was anything else done to the tractor?

Hi,
Good that the arms are tight.
The only adjustment the steering gear has is under the housing. The nut at the bottom of the housing, that holds the arm to the shaft, might need tightening from wear in the steering gear.
The nut controls the up and down movement of the shaft, which has 1 of the steering gears on it.
You can look under the gear, and see if the shaft and arm move up and down any when someone turns the steering wheel back and forth enough to make the arm move a little.

The shaft and nut should have a cotter key through them, remove that, and loosen the nut on the bolt through the rear of the arm, it locks the arm on the shaft.
Tighten the nut gently, if you tighten it too tight, the steering can bind.
You might not be able to get all the play out at the adjustment, the cotter key has to go through the shaft and nut in only a few positions.

I would jack up the front of the Cub at the center, so the front wheels are barely off the ground, then you can turn the front wheels freely from side to side, and check for binding.
If it binds, back off the nut 1 space for the cotter key.
Be sure to tighten the bolt and nut through the arm when done.

If the steering gear still has play after adjusting the nut, the bushings in the steering gear may need replacing.

Below is a page from the Cub parts manual.
The arm is number 25, the nut is number 29 in the pic.

Below is a pic from TM Tractor, the left side of the pic is where the bolt with the nut, and the adjustment nut are. Disregard the shims in the pic.

I got the tractor around three months ago it did not run I had some stuck value fixed that and got it running took it for a drive no trouble then yesterday I put the new tires on drove it a round again and it started making that slapping noise in second gear

Check all the wheel bolts for tightness. Hub to center and center to rim. And also, any wheel weight bolts.
