Thumping Sound
Guys I have not had much fun with the front end of my 1999 4x4 7.3 diesel dually. Well I replaced the ball joints with moogs over the winter. Just recently I my truck has developed a thumping sound that I can feel under my driver side floor board. The weird thing is that it does not do it all the time. But yesterday I noticed it for a more extended amount of time. Any thoughts?
Thanks
Thanks

I'm guessing sway bar end links.
pretty easy fix, if you go with OEM I think this is what you need from parts guy Ed it replace the whole end link.
Energy suspension sells a kit linksy to riffraff energy suspension kit that replaces the bushing, I used the energy suspension and yeha it works but I am thinking about going back to OEM...for some reason the energy suspension kit gets noisy and starts clunking when it's wet? at least on my truck. Other that that it works fine. Maybe I didn't grease the bushings enough when I put them in.
either one of those suggestions should cure it though

Well I jacked it up today and found the problem. Turns out the hub assembly was toast. Bearings were bad. Man the tire had a lot of play in it. Only thing that was weird was when we got it back together after I tightened the brake caliper back on you could not spin the wheel. We just could not figure it out. So my father-in-law noticed that the caliper itself not the pad was touching the rotor. We put everything back together exact. So we put a washer in between the caliper and the rotor to fix it. I am just wondering if the after market assembly was a hair shorter.

OP didn't say what year truck he had.... but I'm betting he hard an early bird.
There are several types of hub assemblies out there, between ABS and non-ABS hubs. However, the early one's have different hubs from the later years. Early hubs are MUCH more expensive than the later years (like double the money in some cases).
You can use the later hubs on the early trucks... just HAVE to change the front rotors (and pads because of the new rotors) to the later rotors because of the difference. So the OP probably put his old rotor's back on and that's the problem.
Ed's site mentions this in his Front Axel kit he sells.
And all of this I know because I've got an Early bird... and my Passenger side needle bearing is... on it's way out... causing the axle shaft to vibrate when i hit a bump. and then the next bump it will stop. If you grab the shaft you can move the shaft up quite a bit.
So I'll have to be digging into this soon... hooray!
