dei Posted January 29, 2018 Share Posted January 29, 2018 (edited) Anyone run into this? I took the wheel nut off my 1958 Limited parts car because I have misplaced the wheel (meant Spindle) nut on my '58 Limited car being restored. Tried to put the wheel (Spindle) nut on it and feels like the threads on the spindle are cross threading. Gave the nut to my son who works at a mould making company to see if the tool shop had a die I could borrow and came back saying they identified it as a metric fine thread. M20 x 1.5 Called a machine supplier here and they have a die that size and in stock but at 55.00 plus 13% thought I'd ask here first. I can't believe a car made in the 50's used a metric thread on the front spindles... Would anyone know the specs on these wheel (Spindle) nuts and spindle threads?

old-tank Posted January 29, 2018 Share Posted January 29, 2018 Drivers' side nut and spindle is left hand threads; sides can not be swapped. 1 1 Link to comment Share on other sites More sharing options...
dei Posted January 30, 2018 Author Share Posted January 30, 2018 Hmm.. I'm going to have to get the other side and give that a try... Thanks for the enlightenment Sir. Link to comment Share on other sites More sharing options...
JohnD1956 Posted January 30, 2018 Share Posted January 30, 2018 Is that how it is on your Special Dei? Link to comment Share on other sites More sharing options...
dei Posted January 30, 2018 Author Share Posted January 30, 2018 Frankly John I was more careful doing the brakes on the Special and kept things in marked boxes for each wheel so not sure. Luckily I have the Limited parts car so will take the same side wheel nut off it and see. I just have to clear away 4 inches of fresh snow to get at it!

JohnD1956 Posted January 30, 2018 Share Posted January 30, 2018 I would think it odd if left hand threds were used on one model. Also on one axle position. So thinking about the Special, do you remember left hand threds on the drivers side front and rear axles? If not what may have happened was some one replacing a broken stud with the left hand thread thinking it was the way to do the job. I know my '56 does not have left hand lug studs on the drivers side, and would think it odd that the Division went with that theory afterwards. But anything is possible. And if it was mine I'd prefer to have both cars set up the same. Link to comment Share on other sites More sharing options...
dei Posted January 30, 2018 Author Share Posted January 30, 2018 As always John thanks for your thoughts on this. Just to be clear though, It isn't the wheel "bolts" if I understand your post that are my issue, it is the actual "wheel nut" holding the bearings and left front brake drum on that is my problem. The wheel nut I took off the parts car came off the "passenger side" thinking they would be the same and trying to put it on the "drivers side" of the good Limited. I think Oldtank is telling me the threads on the spindles are left hand on one side hence will take the drivers side off the parts car (when it warms up a bit) to see if it matches the spindle threads. Seems a simple fix if that is what is my problem, trying to mix the sides... Just a High School auto shop backyard mechanic at work. (never too old to learn and thanks OldTank for the Auto 101 lesson) 1 Link to comment Share on other sites More sharing options...
JohnD1956 Posted January 30, 2018 Share Posted January 30, 2018 My mistake. I thought you were talking the wheel studs. Dump my comments! 1 1 Link to comment Share on other sites More sharing options...

The 63 Riviera has left hand wheel studs on the left side of the car. I don't know about other 63 models, but Buick did go to right hand threads on all four corners in 1964. When tney may have started, someone else may know. Edited January 30, 2018 by RivNut (see edit history) 1 Link to comment Share on other sites More sharing options...
Smartin Posted January 30, 2018 Share Posted January 30, 2018 I don't recall the 58 spindles having any left handed nuts. 1 Link to comment Share on other sites More sharing options...

Going to dig into it later this week and take the other "Spindle Nut" off the parts car if not raining tomorrow and see... I'm wondering if there is something wrong with the threads on the spindle on the good Limited...? Link to comment Share on other sites More sharing options...
old-tank Posted January 31, 2018 Share Posted January 31, 2018 (edited) Yeah, yours is probably unique even though the parts book lists differently: Group 6.022 spindle nut 1941-1960 1319138 RT 1941-1960 1319139 LT Edited January 31, 2018 by old-tank (see edit history) 1 Link to comment Share on other sites More sharing options...

dei Posted February 15, 2018 Author Share Posted February 15, 2018 Just thought I'd come back and confirm what Oldtank stated by part numbers that YES the drivers side Wheel Nut is a left hand thread! Thanks for all the input guys. It's good to have a parts car around too... 1 1 Link to comment Share on other sites More sharing options...
Smartin Posted February 15, 2018 Share Posted February 15, 2018 I must have blocked that out of my memory since I pulled one of those off. Man, that was only a year ago 1 2 Link to comment Share on other sites More sharing options...
