knocking of 2004 f150 fx4 super crew!
Please Help, Engine Problems, 04 F150 Fx4 Supercrew
--------------------------------------------------------------------------------
Hey,
My truck is a 2004 f150 fx4, super crew.
PLEASE HELP PLEASE!
This is very strange and its a problem I want fixed, considering I just bought this truck and want to drive it . What it is, is a knock on acceleration on when in drive or on while accelerating. If you put the truck in park, and rev it up, there is no knock what so ever. It is slightly there at idle. One thing, if you put it in drive, hold the brake, and gas it up to about 1,000 rpm, it knocks extremly fast, and if you hold the brake, and give it a quick accleration to 1,000 rpm, and left of slowly, it has a couple clicking noise right at decelleration. The real noise is, when you just driving, and you at any speeds are accelearting, there is a pretty loud clicking / knocking noise. We have took the front belt of, to make shure it was no front accesories such as alternator and so on. This problem has me stumpped. I know the sound I am almost positive is coming from the engine. I have tried higher grades of fuels, different oil grades, and even we put lucas oil in one change just to see what happened but no luck still there, so we put regular oil back in it. Thats problem one #1.
Problem #2.
When you're in drive, and at a stop, you slowly accelarate to get up to speed, and between 0-5 mph it has a vibration, almost seems like its the rearend just shaking pretty bad, but the rearend has oil. We did chnage the rear wheel seals because of a leak that I had.
