HELP!!!1999 F250 Super Duty 4x4 Popping Sound
I have a 1999 F250 Super Duty 4x4 V10 that just turned 100k miles. It started making a popping noise from the drivers front wheel when I turn the wheels. It is worse when I turn right. I can also feel it in the steering wheel. I was thinking the u joints, because it sounds and feels like a CV joint going out on a front wheel drive car. However, I was told that this would only happen if the hubs are engaged? It does the same thing in or out of 4 wheel drive.
Any ideas? Help!
Thanks,
Dan

The ujoints should only move when the hubs are locked. You might try lifting the front end up and spinning the tires, if the ujoints move you need to double check the hubs are in free. It's possible this is the beginning of a bearing failure, causing the stub shafts to spin and allowing the ujoints to impact the axle. either way, look at it soon and in the air.

If there is slop in the needle bearings, you probably have to replace the hubs. There is another bearing package, but you should be able to hear/feel it rattle while you drive.
For the hubs it's pretty simple, check out guzzle's needle bearing greasing page to see the dis/re assembly procedure. http://www.guzzle7pt3.com/allube.html
The bearing assy behind it is a little more involved, but a good set of regular tools and an afternoon should be all you need.

I have to make a change to my last reply. When I jacked it up the u joint did spin when I spun the tire. It was not in 4 wheel drive, but I checked the manual hub and turned it counter clockwise a little.
Now the axle is not turning when not in 4 wheel and guess what? The popping sound when away! Am I back to it being the u joints that are bad?
When I look online at all of the stuff involved in replacing anything involved with the front axle, my head spins! Lots of stuff and lots of money!! Not sure if I want to tackle it myself.
If it is the u joints, I hardly ever put it in 4 wheel, can I just let it go for a while? Any danger in that?

i would still replace the u joint but when you take the hub off check the wear on it. if it was riding right on the locked/unlock and was just contacting at certain points could have screwed up the the. put it in 4x4 and drive it down the road and see if it still pops first. might just have be clicking cuz it was right there on the line. thats my two cents anyway

Thanks,
I just took it for a spin in 4 wheel drive, everything seemed fine. No popping or grinding, lots of grabbing of tires on the dry pavement. The only worry I have now is that bit of play I saw in the lower ball joint. I know I am going to need to replace that, what a pain in the butt that looks like. I might as well replace the hub and u joints while I am in that far, it all has to come out anyhow!! Crap!
