regarding the bed quiver, is there anything i can do about it?

i have taken to driving with a constant load in the bed (a couple of bags of sand) which seems to help and with fuel at $1.04 a gallon the lowered mpg doesnt bother me. i do have a double tube roll/light bar with the kicker bars which im thinking about fitting (it looks a little better than sand bags!!)

the plugs were a big concern so i got them changed out early for a soild 1 piece design. luckily i have an american mechanic friend here who has quite a bit of experience with these trucks (unlike us brits).

considering the pounding this truck has taken with the offroad driving and general poor condition of the roads here i have to say i dont have any rattles or squeaks…except the terrible bed quiver which can get pretty bad at times

Dremel 7700 (cordless) handy piece of kit for cutting in those tight to reach places…sadly disappointed by the battery running time 🙁

just wondering if you ever got this problem solved.

i have a 2004 F150 (104,000miles) and im having similar problems to you.

Codes:
P0022 – “A” Camshaft Position – Timing Over Retarded
P0300 – Random/Multiple Cylinder Misfires Detected
P0316 – Misfire Detected on Startup (First 1000 Revolutions)
P0307 – Cylinder 7 Misfire Detected
P0308 – Cylinder 8 Misfire Detected

mine started about 6 months ago after a roadside breakdown. the engine refused to turn over and it was assumed that the battery was the issue [battery was replaced], still no turn over. next we assumed that, due to a loss of oil pressure, that the oil pressure sensor had failed and the starter motor had gone bad [oil pressure sensor was replaced]. to jump the starter into life (no replacement part was available) we tried 12v direct to the starter motor where we saw a sign of life from the engine. we then tried 24v direct to the starter motor with no luck. the truck was then stored for 3 weeks while a relacement starter motor was shipped into the country.

[starter motor was replaced] engine still wouldnt turn over. after some deep thought we found the AC compressor had failed and was causing enough tension on the belt to stop the engine turning. [AC compressor was replaced] started the engine for the first time and the engine ran really rough and threw the above codes.

after alot of internet searching we also read about the poorly designed oil galleys in the 5.4 Triton engine and did a full flush plus additives in the oil to help clear the system, this didnt help. next we looked at the VVT system, changed cam sensors and cam phasers again with no luck.

after more internet searching and with a chat with a Ford Mechanic it turns out there is another cause for this which Ford wont admit to. it turns out that if the timing chain becomes lose, even for a split second, it is possible for the chain to “jump” a tooth on the cam shaft.

this can be fixed with a full retiming of the engine which is unfortunately a pricy job. however, i (and a few others in the internet world) have found that if you unplug the cam shaft sensors, and esentially disabling the VVT the truck will run just fine (with the odd misfire) and this is how ive been running mine for 6 months. other on the internet have been doing it for years.

Note: if you take the problem to Ford they will insist on replacing the engine.
