cv castle nut loosening


Recommended Posts

Castle nut loosening has nothing to do with the bearings being bad. This happens for one of two reasons: Either there was dirt or goop on the inside of the wheel hub where the axle enters the hub that has worked its way out hence loosening the nut. The other possibility is that the beveled washer wasn't tight and finally seated itself which results in loosening the nut. Thirdly, it might not have been tight enough to start with--145 ft-lbs is a lot, but you can tighten it even more if you like without damage. Oddly enough when it loosens like this, it even sounds like the bearings have gone bad on that side.

well thats the thing, the cotter pin in in, and i tightened it about a month ago, when i did the cv. today will be the third time i have put a big cresent wrench on there, and stood on it, to get it tight. last time i tried a different conical washer, and flat washer, and it started again. its not like the nut is loosening, the metal behind the nut is shrinking, or the axle is continually getting pulled closer to the nut.

Sounds like the axle wasn't all the way in, or, like edrach said, there was gunk behind it that is getting squished out... also, not sure about the wisdom of the large cresent wrench.. may want to consider investing in a 36 mm socket

I'm with caleb on the cresent wrench. I suspect you're not getting enough torque on the nut with a cresent, even if you're standing on it. A 36mm socket with a breaker bar (and maybe a 2 foot extension with a pipe) is a good bet.

'Crescents are o.k. on nuts that big' (and to torque 145 lb.ft.).........

 

and they call ME "Hillbilly".:brow:

 

 

You're right, they will work...in a pinch, but sometimes a little investment in the proper tool goes a long way. Suit yourself...

 

Just an observation.

if the cresent doesnt slip, and i stand on it, and i am applying pressure 1 foot out, i weigh 145 lbs. see where im goin with this?

 

i didnt fix it yet, but my bearings are shot, and thats gotta be the reason, its getting looser and looser. the center spacer and bearings are getting smaller and smaller.

I was gonna say you could use my 36mm and braker bar but you were already standing on your cresent wrench when I came outside lol

 

Glad to hear you found the culprit. Maybe we can do the bearings and rear disc conversion all at the same time? I've never had to do wheel bearings on these so I could use the xperience :)
