Rob Posted December 1, 2009 Share Posted December 1, 2009 sorry the pic was too big. i believe their buds.the truck is a 96 mr 688s refuse truck.thanksBudd style use an inner wheel retaining threaded nut, and an outer wheel retaining nut also. Both nut seats and the seats on the rims are tapered. The hub pilot style use one nut with a fixed washer to retain both wheels to the hub. The stud holes are not tapered. Dayton hubs are spokes.With either the Budd, or hub pilot style the stud is pulled into the hub from the rear to the front of the hub with a puller. I've seen many studs pulled into the hub using a lug nut but that usually galls the snot out of the threads, or stretches the stud rendering it weak and useless. Rent an installer for this installation, or purchase a mechanical one. They can take a lot of mechanical force to pull them in too..... A Dayton style spoke hub will have the studs screwed into the spokes. You will need a stud extractor if the threads are stripped to grip the body and twist it out. If you can get two nuts onto the threads, jam them together with wrenches and gripping on the lower nut turn the stud out of it's mounting.Be prepared for some busted knuckles as is the norm for me.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

HK Trucking Posted December 1, 2009 Share Posted December 1, 2009 If it's RH and LH threads then it must be the old style Budds.Dayton and Unimount are all RH thread.

macattack Posted December 1, 2009 Author Share Posted December 1, 2009 If it's RH and LH threads then it must be the old style Budds.Dayton and Unimount are all RH thread.so do you think the other side would be the same. what i meant was on one side and one tire there were lh and rh studs. is that normal for the old style bud.i think it would proibably be a good idea to replace them to lh. what do you thinkthanks Quote Link to comment https://www.bigmacktrucks.com/topic/11604-need-to-replace-studs/#findComment-44297 Share on other sites More sharing options...
Rob Posted December 1, 2009 Share Posted December 1, 2009 so do you think the other side would be the same. what i meant was on one side and one tire there were lh and rh studs. is that normal for the old style bud.i think it would proibably be a good idea to replace them to lh. what do you thinkthanksNo sir, not at all. Left handed threaded studs were used on the left side of the truck only. Right handed threaded studs were used only on the right side of the truck. This is only with the "Budd" style cap and nut retaining system. All the hub pilot wheels are right hand thread no matter which side of the truck they are on.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
