ptwothree Posted June 28, 2017 Report Posted June 28, 2017 Anyone know the thread pitch on these? My thread checker shows a very loose 10 per inch. I'd like to replace the nut with a castellated nut and cotter pin. Quote
Dodgeb4ya Posted June 28, 2017 Report Posted June 28, 2017 Thy are a special "Acme" type thread. I'd use Loctite thread locker Red if you feel the need. What's the issue? Quote
Andydodge Posted June 28, 2017 Report Posted June 28, 2017 Also the nut for these should have a large internal shakeproof washer........that coarse thread is to allow grease to travel between the pin & bush, tho' the shiney edge to the thread halfway along indicates some wear to my eyes..........whats the inside of the bush look like?.........andyd 1 Quote
ptwothree Posted June 28, 2017 Author Report Posted June 28, 2017 The shiny area is where I hit it with a wire wheel just to clean it up for the pic. The issue is that both upper and lower retaining nuts were finger tight. I replaced the lower pin and bush assembly on the drivers side. It came with a castellated nut. If I can't find any then I guess it'll be done up with Locktite and the 'shake proof' washers. Andydodge....Thanks for the explanation on the use of Acme threads on these parts...makes sense! Quote
