Does your 4X4 Explorer make nise from the front end ? (also posted on FTE)
Does it sound like your truck is being chased by Seagulls ?
Were you told that the seal inside the bearing knuckle is the source ? Take a look at the following link. It's the part marked #3 in the illustration. Link If so, I think I have the solution which will cost you almost nothing compared to the 3 hours of work + parts that Ford will charge you. The 4X4 has a small brass seal that seats inside the steering knuckle. The CV joint of the front drive shaft goes through this seal and I believe the seal is there to prevent dirt from going into the front bearing/hub assembly (which costs almost $270, mind you). What I think happens is that with time the rubber boot that is protecting the CV joint dries up and rubs against the seal making that annoying noise. Mine was so bad I felt like I'm driving on a pier with 50 loafs of bread on the top of the truck and 100 Seagulls chasing me. Anyway, to solve this annoying problem all you have to do is get under the truck right under the drivers/passenger door. Look at the CV joint and trace where it goes into the steering knuckle. Take some lubricant (I used some WD-40) and spray a small amount of it right where the rubber boot goes into the knuckle. Spray a very small amount and watch out not to spray the brake rotors with it or you will be driving into the fence without the ability to stop. I did mine a few days ago. It's a 2 minute fix which will probably last a few weeks. I used WD-40 just to test and see if I'm correct about the source of the problem. I've been driving the truck for 2-3 days now and there is absolutely no noise anymore. Next time I plan on putting a small amount of grease as the WD-40 will eventually dry out. |
