The Datsun 1200 uses a traditional recirculating-ball Steering Gearbox with behind-the-axle (rear steer) linkage.
Contents |
Terminology
The six ball studs have a Filler Plug on the bottom of each. Replace it with a grease fitting and fill it during each periodic "lube, oil and filter".
- 1. Idler Arm. This bolts to the subframe rail on opposite side from the steering gearbox
- 9. Steering Gear Arm, a.k.a. "Pitman arm"
- 19,20. Side Rod, a.k.a. "tie rod". Left and right hand differ
- 12. Cross Rod, a.k.a. "drag link" or "center link"
- 21, 22, 23, 24. Side Rod Socket Ass'y a.k.a. "tie rod ends". There are four separate parts with left and right-hand threads. Each "socket" has a "ball stud", which is similar to a Ball Joint.
Inspection
You cannot tell by looking if the rod-ends or ball joints are worn. Anything more than 1" play in the steering wheel indicates loose steering.
Of course you'll want to confirm that the steering linkage is tight, because that's usually where the play is. The tie-rod (side rod) ends, ends of the drag link (cross rod), and particularly the idler arm should be inspected.
Easiest way to check for play in the linkage is with the car over the ground/over pit, get some one to wobble the steering wheel left to right and hold each tie rod joint in between your fingers, you should feel no play in these joints...
You can check the steering linkage as follows:
- lie on the ground near the driver's side door, looking at the underside of the car
- reach up and wiggle the steering wheel back and forth (with the door open)
- watch to see if any of the rods move independent of each other. If they do, the rod ends need replacement.
- the steering knuckle, and thus tires, should move with the tie-rods. If a rod moves, but not the tyres, the linkage is worn at that point
- the idler arm should NOT move up and down, only rotate. Replace Idler Arm bushings if ANY up-and-down motion is detected
This can be easier if a mate handles the wheel, leaving you free to inspect the underside, but it can be done without an assistant.
To double check any of the rod ends and idler arm, jack up the wheels and securely block the car, then wiggle the rod end ends forcefully by hand. There should be no play; they are supposed to rotate, but not move end-to-end.
Finally, if in doubt, disconnect the rod-ends, they should move with a firm but smooth drag as you rotate them. If they flop around, they are worn out.
Power Steering
Separating Ball-stud from Linkage
Separating the Steering Linkage for tie-rods, cross-rod, steering arm, knuckle arms or ball joints. To separate a rod-end/balljoint/ballstud, use one of these methods:
- Pickle fork and hammer
- Tierod-end joint puller
- Two-hammer method
- Prybar and hammer
CAUTION Never hammer on the threaded portion!
Datsun recommended the two-hammer method. Pickle fork is perhaps easiest but may damage the joint boot. Puller method is very nice.
WARNING Heating forged steering components is a VERY large no-no
Steering Gearbox Arm
Use the hammer methods or a gear puller.
Do not place a piece of pipe or wood on the steering rod and smack it hard with a big hammer. This can bruise/dent the worm in the steering box and compromise the box's smooth operation.
Two Hammer Method
- Remove the cotter pin & loosen the castle nut as far as the end of the ball-stud. This will hold the part from dropping all the way when the joint is popped apart.
- Hold a large hammer (e.g. 8# sledge) against one side of the part with the hole, and smack the other side with a 2nd hammer. The joint will pop out of the hole.
The first hammer is to absorb the blow so the part doesn't move.
NOTE: You have to smack it very hard while holding the stationary hammer at the same time AND not hit any other body or suspension parts. To make it easier, have an assistant hold the stationary hammer.
Sometimes people are not successful, usually because the hammer blow is not square to the stud axis and the energy is lost. But it will come out, regardless of condition, age, what-have-you, when done correctly. This is the method master mechanics use.
Pickle Fork
NOTE: Pickle fork may damage the joint boot. Great way to remove old bad parts, but the other methods are suggested for reusing the parts.
Pickle fork (wedge) fits many sizes of joints. For a Datsun, a medium size pickle fork is about right.
- Remove the cotter pin & castle nut
- Insert the fork between the two parts
- Whack the hammer very hard with big hammer. Use at least an 8# sledge. Better is a 12# or 16# hammer.
TIP: If possible, insert the hammer inline with the steering linkage, so that your hammer blow doesn't deflect the linkage sideways. Moving the steering wheel first will help line up the linkage to where you can hit it straight on.
Ball Stud Puller
You can use any small gear puller. A puller fits only certain sizes, but doesn't damage the grease covers. If using a generic puller, make sure the shaft when turned does not damage the ballstud threads.
- Remove the cotter pin & loosen the castle nut as far as the end of the ball-stud.
- Insert puller into correct position
- Turn puller nut with wrench or socket until the joint pops apart
- Remove castle nut fully
Lever and Hammer
- remove the split pin and nut
- Insert the lever (prybar, crowbar, etc.) to apply a medium pressure on the two pieces, as if prying them apart. But the leverage is only to apply pressure, NOT to actually separate them.
- While keeping pressure on the parts, using two hammers, hit opposite sides of the hole simultaneously. You don't need to use Big Hammers.
What you are doing is deforming the hole out of round for just a second which breaks the tapers bond from being jammed together, this will spit the ball stud off. You dont need to pound very hard, just keep tapping away.
Idler Arm
See main article: Idler Arm
Cross Rod
The Cross Rod is also known as center link or drag link. It includes two ball stud joints which can wear out if not regularly lubricated.
