I've read the manual and I don't have the "special" tool to do this. I'm sure someone has done this without it. Will a crow's foot 19mm or 3/4" work? I have more tools than most but, no crow feet. I have the tire off, on access there. I removed the plug wires and the heat shield and can see it. I have a 3/4" wobble scoket which is low profile but, the head is still too close. Will I need to bend a 19mm open end wrench? What is the trick here? Surely someone has done this before. Thanks

I had my steering gear adjusted about five years ago. I'm not 100% sure, but I think the tech who did mine used a crows foot for the jam nut.

I do know he had a cut off allen wrench for the adjusting screw. He put it in an appropriately sized stubby GearWrench to make the adjustment. Used ShiftNob's super glue trick to hold the allen in place!

Thanks, I'll pick up a crows foot tomorrow and a throw-away 6mm allen.

Remember...Counter-clockwise to tighten the box.


That really doesn't sound right.

Yea, I read that part. Seems 1/4 turn then give it a try seems to be the thing.

Yes. Don't forget to re-tighten the lock nut.

Just a follow-up so i don't make Nobby's shit list.:D

I bought a 3/4" crows foot 3/8 drive and a 6mm allen with a ball end. The ball end is necessary to get at the allen at an angle. Cut the end off the allen and found a 6mm socket, layed a piece of paper towel in the scoket and pushed the allen in and hit it with a hammer to set it tight. Now I have a 6mm allen socket with a ball end.
The adjustment was suppose to be 1/4 turn at a time, but when I broke the jam nut loose my allen turned too. I just turned the allen set screw ccw until I felt something inside touching, then backed it off a 1/8 to 1/4 turn and jammed up the nut. Drives much better and all my slack is gone.
Only think I had to remove is the plug wire and the manifold heat shield.
Looks harder then it is.:thumbsup:

Due to popular demand I have retired the "shit list". It was just getting too long.
Good wrench, Nascar.

I am marshalling the tools necessary to adjust my steering box, having finally learned to do this before starting the job.
How long is the 6mm hex socket? Is it a stubby or full length?

I bought a full set of metric ball end allens. I cut the 6mm off about 2" on the ball end and put a piece of paper around it and hammered it in a 6mm socket 1/4" drive so it would stay. View attachment 6

Supplementary Question: Will a stubby (about 2" overall, incl socket) work, or is a longer one needed?

Yea, shorter will work fine as I put about 24 in. of extention on the drive to get the ratchet up and out of the engine bay. The ball is the important part of the tool to make access at an angle.

Rainy day today ... decided to put an hour or so into getting rid of the slack in my steering by tightening the box.
Right! ... 8 hours later ... release oil, crows' feet, box-end sockets, extensions galore, working underneath (per manual), working from above (per NF), impact wrench, cuss words aplenty, occasional help .... I can't get the flipping jam nut loose.
Half the problem is getting a good grip on the nut from the awkward approach angles. Other half is the Crazy Glue and Atomic Wrench the last guy seems to have used on everything. Witness my saga with the Pitman arm, which defeated even the local front end specialist and his tools.
Now it's personal. Tomorrow the torch. Maybe I'll set the effing thing aflame. Suits me.
I could flee to a place where they actually have summer.

Your car is too nice to dismiss so randomly.

Have a drink, for Molson's sake.

Can I come up to watch this? Could be entertainment worth the drive.

I think I am going to have to give up.
I believe some previous dolt has rounded the jam nut somehow.
I have tried every tool in my box and I just can't get a solid grip on it, from above or below. I have scouted the local tool stores for solutions, with no luck. Nobby's recommended beer treatment was no help.

I can't remove the steering box to work on it, for the Pitman arm won't yield either.

I am afraid to remove the exhaust manifold for better access in situ; I just know those bolts will shear off.

Any ideas?
Do they make 2 foot long needle nose vise grips?

I'm like an old dog with a bone.
I just tried to loosen a couple of the manifold bolts and was surprised how tractable they are. Maybe I will try to remove it after all.
So, what pitfalls await me in R&R the driver's side exhaust manifold?
