On the little tike car where the front wheels fit i need to get 2 new locking nuts or locking washers that fit on top of the metal rods

Vt commodore steering Rack boots always rip and tear,the racks always tend to leak from the internal seals.
So if this the case with yours I would recommend you just get a reconditioned steering rack and fit it but once the rack is replaced you will also need to do a wheel alignment.
steps to change rack .
1.raise vehicle on hoist
2.remove front wheels
3.remove tie rod end split pins
4.undo tie rod end nuts and inner nuts on rack ends
5.release tie rod end from hub.
6.centralise steering wheel and remove keys from ignition
7.count the number of turns on each side that tie rod come off and write down .
8.undo the 2 metal pipes that go into the rack feed and return lines and make sure u have container under the vehicle to collect old fluid.
9.undo the 13mm nut and bolt that mounts the rack to the steering colum shaft.
10.undo the 2 *19mm bolts and nuts that mount the rack to the crossmember.
11.gentle wiggle the rack and it will come away.
12.follow these steps in reverse when fitting new rack.,make sure you replace the oring seals .
13.you will need to get a wheel alignment done..

That part is called a push nut. You can buy them at most hardware stores in their specialty fasteners area. You will need to know the axle diameter so you can get the correct size.

Strut and Spring Assembly Removal

1. Raise the vehicle on a hoist.
   

1. Remove the front wheel and tire assembly.
   

1. CAUTION: To avoid damage to the 6mm drive hole in the front stabilizer bar link ball stud, do not use an Allen wrench to break loose or tighten to final torque the front stabilizer bar link-to-front shock absorber nut.
   Remove the stabilizer bar link retaining nut and disconnect the link from the strut.
   

1. CAUTION: Do not allow the halfshaft to move outboard. Over extension of the CV joint may result in the separation of internal parts, causing failure of the joint.
   Remove the strut assembly-to-steering knuckle pinch bolt. If required, slightly spread the steering knuckle to ease the removal of the strut. Pry down on the lower control arm and roll the strut base out of the knuckle. Do not pry on the halfshaft, as damage may result. Wire the steering knuckle up to prevent the halfshaft from moving outboard.
   

1. Partially lower the vehicle.
   

1. Support the strut assembly and remove the top three mount-to-strut tower nuts. Remove the strut assembly from the vehicle.
   

1. CAUTION: The strut assembly is under spring tension. Attempting to disassemble the strut without properly compressing the spring can result in injury.
   Using a suitable spring compressing tool, slightly compress the strut spring to relieve initial tension. Loosen the upper rod nut. Continue to compress the spring until the tension is relieved. Remove the upper rod nut.
   

1. Remove all upper mounting parts, coil spring, and coil spring isolators from the strut and save them for reassembly. Carefully note the position of each part during removal to ensure proper reassembly. Inspect each part for wear and damage as it is removed.
   

Installation

1. CAUTION: The bearing and seal assembly is press-fit onto the upper mount. The mount washers must be installed in the correct orientation.
   NOTE: Be sure to check the spring insulator for damage before assembly. If the outer metal splash shield is bent or damaged, it must be carefully bent back, so it does not touch the locator on the bearing and seal assembly.
   
   NOTE: New gas struts are shipped with the rod in a locked down position. To extend the new strut, remove the external tie down and/or rotate the upper end of the rod, counterclockwise.
   
   Install the coil spring insulator, coil spring, and upper mounting parts to the new strut assembly. Make sure the spring is correctly seated in both spring seats.

hope this helps

try gripping the axle with a pair of vise grips and use a pair of slip joint pliers to twist the cap nut off the axle.worked for me!

Jack up the front of the vehicle remove the wheel. Put a jack stand or similar under the side of the vehicle , dont just rely on the jack to hold it up. remove the split pin from the nut on the joint. Crack off the locking nut from the tie rod to the end. Dont undo it just back it off less than 1/4 turn. Undo the nut that the split pin came out of. Leave it on a couple of threads. place a rod,bar or lever of some kind to put pressure on the tie rod end away from its position . The end has a tapered fit where you have undone the nut. Hit the side of the steering arm that the rod end goes through with a hammer. You will need to hit it quite hard a few times ,this will jar the tie rod out of the taper. Take the nut right off then unscrew the rod end from the tie rod. Place the new and old tierod end together to make sure they are identicle. screw the new joint onto the tie rod to the same position the old one was. place the tapered end through the steering arm. tighten the nut then fit the new split pin. Tighten the lock nut on the tie rod to the rod end. If it is a greasable joint grease it with a grease gun. You may wish to have a front wheel alignment done. Replace the wheel and let the vehicle down. Happy motoring. If this has been usefull Please Vote Jeff

I have dealt with many of these metal push nuts, best thing is to break the plastic off with a needle nose or regular pliers and then that will expose the metal push nut, then you can bend that with the pliers and pull it off and swap the tires to the correct sides, keep in mind this will ruin the push nuts and new ones will need to be ordered off ebay or something similar

You can try these push nuts from this site:

I don't know what size of axles you have on your toy, but these fit my little tikes hummer wheels.
Hope this helps

I would take a pair of pliers and pull off the push nuts.
You have to replace the push nuts with new ones, but when you purchase the little tikes hummer wheels from http://www.shopjandl.com/kids---baby-ride-on-toys-little-tikes.html
they provide the push nuts with the wheels

The caps are a type of "acorn nut". Check a local hardware store (not the big guys) for this type of fastener and bring the shaft with you to get the correct size. These should not cost more than about $.50 each.
