I have a 79 ford f-150 4X4 and it has recently begun to make a ticking sound kind of like a rock in the wheel. I am almost positive it is not the engine. The sond speeds up as I go faster until it is drowned out by engine noise. Any thoughts? Wheel bearing? Drive shaft? It souns like it is coming from the front left and It stops as I get below 10mph or so. And I can't walk fast enough beside it to see wear it is coming from.
I have a similar ticking and it was the speedo gear. Once I found it you could watch the speedo a slower speeds and see the needle jump every time it "ticked".
Do you have hub caps? Rocks in the hub caps will do that too. Okay Okay I know, but you never know. We had a "piece of" Dodge at work with hub caps and nobody could figure out that clicking sound until I stood outside while someone moved the truck slowly and I found the rock thing.
No, no hub caps, but I just realized that I have been driving around about three months w/ the transfer case in 4hi. The hubs were unlocked though. Will this have any bad effect?

I would pull the locking hubs and make sure they're working properly. They will make the sound you described if they're not disengaging all of the way. Sometimes they just need to be cleaned and lubed (not packed). If one has hung up or trying to engage you could have a spring that has expanded due to it being twisted, not allowing the locking hub to fully disengage.
I have a ticking on mine too.. mine is 79 2wd. initially i thought it was something in the engine.. and it scared me as i am not much of a mechanic and i now reside in a new town where i dont know anybody. so if i break down i'm screwed.
i have since determined that it does not do it unless i am driving.. and i only hear it between 10-40mph.. that may be because when i am faster i cant hear it. i suspect the hood is cause of mine.. but not real sure just yet..
trying to have a rolling restoration project is proving costly and worrisome.. had i known when i got the truck i'd be moving, i would have not gotten the one i did.
oh well, i still love my truck.
My experience with the "ticking" has been that it has almost always been a sticking valve - and an oil change/fill has fixed it a lot of the time. An engine that uses oil and gets low tends to do this a lot.
Try a top engine clean with Seafoam. The stuff really works and does a great job removing old oil build-up.
jack up one side at a time and spin the wheel if the noise is ther take the wheel off and spin the hub . if niose take off brake caliper and spin the rotor.
Since SeaFoam was mentioned...
What is it that you actually do with that stuff? Does it go into the tank or into the oil? or both?
It's one of those petroleum based products that can go in the gas tank, oil, and intake. I found that it works best at removing intake deposits if you use manifold vacuum and suck the stuff into the intake manifold and let it sit for about 20 mins. Fire the vehicle up and watch out! It will look like your fogging the neighborhood.
I had lots of valve noise in my old Jeep CJ and the stuff cleared it up. I was a real skeptic about something making a real difference, but the stuff really did a good job.
