Does anybody know the torque figure that's used to tighten the pitman arm or drop arm (seen it called both) to the steering box?

It's the big 40mm nut that's on the bottom.

Have searched RAVE but can't find it for some reason.

I can't find it anywhere either but having taken one off, I'd say bloody tight. At least a good heave on a 4 foot breaker bar.

I have no exact idea to which parts you refer (sorry), but I can offer:

  • Drag link clamps nuts and bolts 8mm 22 Nm or 16 Lb. Ft.
  • Drag link clamps nuts and bolts 10mm 47 Nm or 35 Lb. Ft.
  • Drag link to drop arm and swiwel hubs nuts and bolts 50 Nm or 37 Lb. Ft.
  • Drag link to drop arm nut 50 Nm or 37 Lb. Ft.

These along with others I have it the workshop manual in Section 06 Torque Values, 57 Steering, page 60 or 1361 in my PDF file.
Have fun!

The figure he is looking for is drop arm (or Pitman arm) to steering box output shaft. The one that doesn't appear to be listed anywhere.....

I can't find anything about the torque on the P38 anywhere.

However, Defender torque is 176Nm or 129LB/FT so I reckon I'll just put some loctite on it and go for something similar.

Great - thanks!

I’ll get the torque wrench out and tighten it properly this evening then.

Looking forward to driving it with the brand new steering box on it. Once my L322 is off the ramp we’re going to replace all the bushes on it too so it should be spot on then.

you have a torque wrench that reads that high , i my case it would be a strong arm on the nut ,a piece of pipe on the strong arm and a foot against the tyre and tighten until you grunt . that's how tight i would do it .

Just to confirm it has been torqued and the washer on it peened over the nut and the drop arm. Has noticeably improved the drive - much less steering correction needed.

Next job is bushes and it should be great then. Any P38 I buy I rebush the suspension on fairly quickly usually as it makes a big difference and when coupled with a new steering box that I've put on 2 before it should have it driving excellently.
