Causes of broken ball joints

This is the second time on TWO different trucks I've broken a ball joint and left both trucks sitting on the frame.

First was my 94 GMC 1/2 ton stock height. It was my daily driver. Mostly in town. Steering got stiff right after new tires were mounted. Drove it 10 miles, and luckily in a parking lot at 5 MPG it snapped (drivers side) and shoved the wheel up under the fender.

Second time was on my 1995 Silverado 1/2 Ton that is lowered 4 inches. In my driveway at 3 MPH, it snappec and shoved the front tire up the fender (driver side). Kinda scary if it happened at speed. What causes this ?

Re: Causes of broken ball joints

Does your state have annual inspections? If they don't, YOU need to check out your steering and suspension every year. Stuff wears out. Nothing lasts forever.

Did the ball come out of the socket? Or did the stud shear?

Re: Causes of broken ball joints

yeah just gotta shake down the front end every once and a while depending on how far you drive. my 1990 with 225k on it still has the original ball joints in it, its amazing theres no play in them yet. today im throwing my winter tires on it so ill be sure to inspect everything

I've never lost a ball joint or known anyone who has.

Re: Causes of broken ball joints

OEM ball joints have no lube fittings ( well, in my '88 - they may have added them later on in newer trucks)

I had an upper fall off while parking, back in 2001. ( couldn't find what that squeek was)... soon found out !!

I just replaced EVERYTHING on my front suspension & steering 2 weeks ago. Including upper control arms, etc.

Truck feels like showroom!!

The ball joint tends to fail completely when the most stress is forcing it sideways, as in a parking maneuver .
