The most often neglected part of the Classic Volkswagen Drive-Train is the Steering Box. The 113415061C, which is the factory OEM part number, is the most common steering box used. It will work with *All Type 1's, Type 3's, Type 181's and anything that came with a Ball Joint front suspension.
Adjusting the steering box with the adjustment on the top of the box is often over used. As a whole, the steering box is responsible to 40% of the steering wheel play/creep in the steering system. Crazy, right? There is SO MUCH MORE that is responsible for play/creep but we as consumers assume, the steering box is the reason.
What plays a role in play in the Steering System?
Steering Wheel connection to the steering shaft (proper torque)
Steering Shaft connection to the male steering tee (proper torque)
Male steering tee to the rag joint (rubber doughnut) (proper torque)
Rag joint to the female steering box tee (proper torque)
Female steering box tee to steering box (proper torque)
Steering Box (proper adjustment - set to spec by the PRO's)
Steering Box to beam connection (proper torque)
Steering Box to pitman (drop arm) connection (proper torque)
Pitman arm connection to the inner right tie rod end (proper torque+creep/deflection in the joint)
Pitman arm connection to the inner left tie rod end (which needs to be bent) (proper torque+creep/deflection in the joint)
Steering Dampener (with or without)
Tie rod Ends (4x)
(Just because it is new does not mean the quality control (QC) of each
manufacture is equal to one another, they are all different)
(proper torque+creep/deflection in the joint)
Left inner tie rod end to tie rod (proper torque)
Right inner tie rod end to tie rod (proper torque)
Left outer tie rod end to tie rod (proper torque)
Right outer tie rod end to tie rod (proper torque)
Left outer tie rod end to spindle
(proper torque+creep/deflection in the joint)
Right outer tie rod end to spindle
(proper torque+creep/deflection in the joint)
Upper Left Control Arm to Beam engagement (play/creep in the rotating system - arm to bearing/bushing)
Lower Left Control Arm to Beam engagement (play/creep in the rotating system - arm to bearing/bushing)
Upper Right Control Arm to Beam engagement (play/creep in the rotating system - arm to bearing/bushing)
Lower Right Control Arm to Beam engagement (play/creep in the rotating system - arm to bearing/bushing)
(Link Pin Equipped VW's)
Link pins to arms (proper torque)
King pins (proper reamed fit to bushings along with proper thrust to the carrier)
Drum or Disc Bearing connection (correct thrust on the bearings)
Lug Nuts (correct lug nut to wheel along with proper torque)
Tire load rating or tire pressure (less pressure, more sway, more pressure, less sway)
(Ball Joint Equipped VW's)
Ball Joints (4x)(Just because it is new does not mean the quality control (QC) of each
manufacture is equal to one another, they are all different -
Once the joint is pressed in, it need to be broken in to have the proper thrust in the joint)
Ball Joint connections to the spindle (proper torque)
Drum or Disc Bearing connection (correct thrust on the bearings)
Lug Nuts (correct lug nut to wheel along with proper torque)
Tire load rating or tire pressure (less pressure, more sway, more pressure, less sway)
Crazy to think how much contributes to the overall steering experience. Click on the complete details tab to understand what puts this PRObuilt HD Classic VW steering box, in a league of it's own.

What's recommended?
- If you have a pre-1961 Type 1 VW, and you still have the original steering box, your will need a 1962 through 1968 steering box pitman/drop arm. It will have the appropriate gear and tie rod end holes. One is available as an option in the drop down menu.
- If your hardware has seen better days, pick up the optional install kit that comes with stainless steel ARP hardware and the steering box clamp that is powder coated to match.
- If your rag joint is looking....ragged, it is time to update to the OEM PRObuilt version found here.
- With the help of a buddy, audit the entire steering system on the Classic Volkswagen by one person rocking the steering wheel and the other checking the connections while the vehicle is on the ground.
- If you are looking for a more OEM look, opt for the OEM cap or check out our OEM PRObuilt Steering Box here.
Kewl Features
- Greaseable zerk
- Gun Blued exposed steel components
- Powder Coated Case
- The serrations on the worm gear are sharp and will allow for proper
adhesion when the clamp is tightened, something the aftermarket boxes
lacked.
- Upon
receiving your PRObuilt HD Steering Box, it will be filled with Corn
Head Grease and it will not need to be serviced in your lifetime. It
will not need to be adjusted out of the box. If you have more or less
place after installation, you need to check out all the other
connections that play a roll in the steering system.
FAQ
- Do I need to fill this steering box with grease? No. It comes filled with the correct amount of Corn Head grease.
- My steering box has play in it, should I adjust it? No. Check all the other steering system connections first, this is often over-looked, even the proper torque on the connections has been a leading cause of "play" in the system.
- If everything else in my steering system has been audited and checked, and still has play, can I adjust it? Call us first, 1-623-518-3537.
- What can I do with my core steering box? If it has a VW logo on it AND looks similar to the one that is replacing it, the PRO's do have a Core Parts Program here to get the core coming to us. The PRO's DO NOT want any TRW, Ampri or other brands in any fashion.
