I agree with Steve use a correct length spacer and a tight stub axle nut! . Honestly, I don't know HOW MANY TIMES we have to say the stub axle nuts must be TIGHT!!  This strengthens the stub axle assembly. Far too many stub axles have cracked and broken because people still tighten the stub axle nuts "finger tight ". This is WRONG and is simply NOT good enough.   Jim Buell article is referenced, read Second Edition, page 24, says "you must torque up the stub axle nut tight etc" . With a very small note saying "A special thanks to Bob Grunau for the information used here " .   PLEASE Torque to 75-85 ft-lbs with 5/8" BSF original nuts or 125 ft-lbs with my 3/4" NF inserts. Yes this requires shimming or replacing the bearing spacer.   Don't know why I am saying this so LOUDLY!! And so often.  Stupid on my part as I make and sell replacement stub axle inserts and can repair and exchange cracked steering knuckles. See attached list. Loose nuts, busted stub axles, more sales!!   But for safety sake, please tighten stub axle nuts .   Bob Grunau 150 Pinewood Trail Mississauga, Ontario Canada, L5G-2L1 905-274-4136 grunau.garage@sympatico.ca

With the original bearing setup there will usually be a slight amount of play and this is ok.  With a tapered bearing conversion there will be virtually no play, as this is adjusted out with the aforementioned shims. - Steve Simmons, TC8975 On 4/9/2014 7:17 PM, bdavispics@yahoo.com wrote:  

I have a question regarding the front wheel bearings. I've read Jiim Buell's article on the TC Front End and used it when setting up my TA's front end back in the Fall. Since then I've probably driven less than 200 miles. However, a couple of days ago I took hold of the top of the front wheels and gave them a firm shake. I could hear a click with each forward and backward motion. It was slightly more pronounced on the Off side than the other but it bothered me and I removed the wheel and rechecked the castle nut today. I don't remember leaving it loose enough (with split pin removed) to easily turn with my fingers but that is what I found. I can tighten it and remove the click so I know that's where the movement/clicking is coming from. Buell says .005 gap there is about right. I've also read lots of 'how-to-set-wheel-bearings' on the internet but the question in my mind is just how loose can these be and still be okay. Will .005 clearance allow you to hear a click when the wheel is shaken? Or Should I be removing a slight amount at the back of the castle nut to allow it to pull up 'finger tight' in order to put the split pin in ...but without being obviously loose? Thanks in advance for any comments. Cheers, Bill - Nashville, TN
