does anyone know what this is please

I finally got a torque wrench and sockets, so I'll be retorquing my nuts (so to speak) this weekend. A coworker pointed out you can't really tell what they were initially torqued to, as it takes additional torque to overcome the sticking friction when removing them.

 

Yes, that's true. Break each loose, one at a time, and retighten. Always go in a star-shaped pattern, rather than 'round the circle.

 

Actually, you can. First loosen them, and then re-tighten to the exact same position. (more trouble than it's worth)

 

I hadn't thought about this next step. I was reading the statement as "the peak torque required to loosen the lug nut is not a reliable indicator of the torque to which it was tightened."

With a click-type torque wrench it would probably take a number of tries to get it close, but if I had a good enough reason I might take the trouble. Perhaps if a wheel fell off and I needed to document the remaining, but I don't see myself making the effort under any normal circumstances.

 

In the absence of a setting (or visible corrosion on the bolt):

Start low and wait for the click. Repeat, with an increase in setting of 2, 5, or 10 depending on how big the bolt is (6, 8, or 10mm), until the bolt starts to move without the wrench clicking. Make a note and retighten to that setting

Note: this approach should never be used with stretch bolts...

 

Let's hope Jag didn't use stretch bolts for the studs. That's something only the French would do. (renault dauphin). lol

 

Does anyone what MM socket is needed to remove the lug nuts / bolts? Just bought an F-Type and want to have a small tire emergency kit ready in case I run over a nail.

i have never retorqued my nuts intentionally. There are none so pithy as Dave. Love ya.

 

Keep in mind that there's an emergency compressor and flat seal goop included with the vehicle....under the trunk/boot panels.

Yes. But I'd hate to ruin an otherwise perfect tire by filling it with goop when I could simply punch a plug through a nail hole and refill the tire with air.

Will the compressor work without putting the goop into it? It looks like you have to screw in the goop first? I confess I haven't tried the compressor yet.

 

Compressor works without goop. I have used it to top off the tires at home, avoiding the need to hit a gas station.

i didn't know that the goop would ruin the tire though. Can't plug once it has been used?

 

I was under the impression that once you use the goop or any "fixaflat" type of bandaid, that you need to drive to the tire shop slowly and the tire then must be replaced. Maybe I am wrong?

 

....and once you get your hub centric spacers, there's 40 of the blighters to do!
