Tie rods - impossible to get out !

Post by David V » Mon May 21, 2018 1:53 pm

I have to take my steering tie rods and Pitman arm off to finally put my winch on. To put the upside-down Pitman arm on.
The tie rod ends are solidly stuck in the arm. I managed to get the passenger side one off using a bearing puller that pulled it up from the arm but the other one is solid. I have tried, WD40, heat and a little brutality but don't want to screw the threads up on it. The bearing puller actually snapped it's threads so it's out of action.
Anyone got a tip or is there a tool that I could use or buy that would get the job done ?

I've now seen that there exists a tie-rod remover tool. Anyone know a good one ? Are there different sizes ?

Remove the split pin & loosen the tie rod nut about 4 full turns.
Get 2 good solid hammers as heavy as you can handle or will fit, each squarely on either side of the steering arm.
Hold 1 tight [sometimes a friend may be helpful] & whack hard with the other.
1 or 2 good whacks, girly boy hits are not allowed, & the tie rod/s will have popped & be loose.
By using this method what you are doing is temporarily distorting the steering arm taper the tie rod has been pulled & locked tight, into.
Never ever hit on the tie rod threads or nuts.
Most of these tools are next to useless, some even damaging parts.

(Artificer beat me to it!)

Two equally heavy hammers, on held to one side of the pitman arm next to the tie rod end stud, and whack the other side of the pitman arm with the other, (if you don't have equal weight hammers, the heavier one is the stationary one). Basically, you are trying to pinch the pitman arm 180 degrees on each side of the tie rod end, the shock of the hit will separate it without damaging the boot, tie rod or pitman arm (or knuckle)

Kinda like this, but I put another hammer on the other side of the pitman arm to help the shock effect:

The tie rod separator works well, (most times). Sometimes you can get a loaner one from a parts store like o'reillys:

Often it still won't pop with one of these so a little whack on the pitman or knuckle will pop it loose while under tension.

I use a big rectangular chunk of steel that weighs about ten pounds that I hold on the opposite side of where I whack the side with a ball pein hammer. Acts as a portable anvil, sort of, and builds up your left bicep.
As stated, pullers don't work unless the end is already loose. ish.

I use two 2# Machinists hammers, usually get it on first whack. Some use what is called a "pickle fork" but I would not reuse any tie rod end after a pickle fork was used.

Unscrew the bolt until level, or just above level of the top of the threaded shaft. Use an air chisel with a blunt point on the top of the threaded shaft. If careful they will break loose.

You beat me to it. I find this easier than the twin hammer method (which does work though). The only thing I'd add is that I like to put a hydraulic jack under the arm, as close to the tie rod as possible, as a support. Jack it up just enough to support it, no more.

OK I got it. You hit the steering arm and not the tie-rods. I didn't think of that.
Will try later !

Good videos.

This is the twin hammer method, not the blunt-point air chisel method. Don't hit the steering arm with the air chisel.

One hammer is used as a back up and held tightly against one side of the arm where the tie rod end tapered pin goes thru, then use an identical hammer to give the exact opposite side of the arm a sharp blow (don't be bashful), it sets up a resonance that pops the tie rod end from the arm. Loosen the castellated nut about 1/8" first.
And if the hammers are not the same weight, use the heaviest as the back up and the lightest to strike with.
