Wheel studs bigger than 9/16?!
To start out with; I'm new to DF If this thread is not created in the correct area of the forums - My apologies!
I own a 2005 dodge Dakota quad cab, V8 4.7L, since 2005 I have had problems putting the lug nuts back on and have been told that I over torque them... OK then.
After further investigation, I obtained a tap and die set to try and fix the 9/16 x 18 threads for both studs and lugs... OK, sounds easy enough, right? The die was to small, and the stud has a bigger diameter. Now stumped, I went back to Napa to get another Die to make sure, and I got the same results....
The studs are slightly bigger than 9/16. 9/16 thread size is listed in the parts inventory at Dodge and napa auto parts but the ones on my truck are bigger!
My 2005 dodge Dakota rolled out fresh with bigger studs but had 9/16 lugnuts forced on all 4 wheels. As a result, for the last 6 years I have had constant issues with cross treading the lug nuts resulting in destroyed studs or lugs. I have replaced all 20 lugs but soon after the cross treading re occurs.
3 of the 4 wheels there is missing lugs. The front left wheel is being held on by only 3 lugs. Any suggestions on what to do, Any known recalls issued for this problem?
Personally, I think they installed studs that were meant to go on a Mitsu raider (just a guess).
I can get new wheel hubs, they come with the studs already installed. Plus I would like to get ALL new lug nuts again.
Or, I could change the studs (much cheaper but more work).
Or... perhaps I should check the mitsu raider parts and order one of their lugnuts to see if it'll fit!
Any more ideas on what I could do? Thanks in advance!

the lugs on the raider are identical to the dakota. that is certainly not the issue.
My guess is, the first time you over torqued them, you stretched the threads on the studs, thus the new lugs will not thread right.
New studs are a bit of a PITA, but your going to need them. (Thats my best guess anyway.)

You can replace just the studs, its a pain in the ***, and I recommend a mechanic to do it, unless you are mechanically inclined and have access to a hydro press. I also suggest going to solid gorilla lugs.
Awesome! I appreciate the info!
No one finds it odd that a 9/16x18pitch die will not fit around the stud (a stud that is suppose to be 9/16)? This, stumped the napa tech also. the tip of the stud will not fit into the die lol.... I'll try and get some pictures uploaded! I was going to change the studs but then if the holes are bigger than 9/16 in the hubs, then buying the correct size stud for this vehicle will be small.

I can get a Ball Joint/Pitman Arm Puller C-4150A to remove and press the studs but they want 115.00 for it
. I looked at the gorilla lugs, I would defininately get those. Thanks.
