Introduction: Greaseable Steering Joint for 24v Grave Digger Power Wheels
If you've been following along, I've been building this ridiculous Power Wheels monster truck for my son with a variety of modifications to make it even more awesome. The next set of mods will culminate in a new drivetrain with real rubber tires, basically making it into an electric go kart. This article will cover a minor steering modification.
A few people have reported binding in the steering and difficulty turning the wheel. I've found that the bushing on the steering spindles can have a lot of friction and get bound up. I took ours apart and lubed it, problem solved. To make lubing it an easy task, I decided to add a grease zerk to each steering spindle.
Step 1: Determine Size and Thread Pattern of Grease Zerk
I had a handful of new and used grease zerks in my shop parts bin, so I decided to use them for this project. I measured them with my thread gauge and determined that they were 1/4 x 28 threaded fittings. I busted out my handy tap and die set and found the proper tap for the job.
Step 2: Drill a Hole
Since the zerk will use a 1/4 x 28 tap, I needed to drill a 3/16 hole in each spindle housing. These frames are made from steel and this part in particular is fairly hard to drill. I started with 1/16, then worked my way up in 1/16th increments until I had the proper sized hole.
Step 3: Run the Tap
After you have the hole drilled, apply a small bit of cutting oil to your tap, then carefully start threading it into the hole. Once it goes in straight, it's a fairly simple task.
Step 4: Screw in Zerk and Grease It Up!
Now that there is a nice, clean, threaded hole in our spindle housing, we can screw in a grease zerk. Then we can re-install the spindle and apply grease with a standard grease gun. This might only be necessary every few months with a lightly used ride, but with our extreme mods, I wanted to make service as easy as possible.

Please help. My sons 24 volt gravedigger is having issues and I am clueless and I even had an electrician to come look at it. The battery and the truck runs perfectly. All the sudden the lights, horn, and music just stopped working. The electrician said the lights etc were getting power but he didn't know. Help
Question 4 years ago on Introduction
I too am working on a gravedigger project my project involves running a Toyota Tundra body on a grave digger chassis. How are you planning to convert over to a full blown electric go kart? I too am putting pneumatic v tread tires on

I haven't written an instructable for it yet, but here's a build thread on how I added rubber tires. http://imgur.com/gallery/jqq8QQ4

I too bought 16x6.5-8 v tread tires for my power wheels build I’m curious did you go with the 5 7/8 wide rims?
