Thread: 02 fx4

I heard today that in 02 ford had problems with the motor sending plugs through the hood is this true?

I don't think through the hood lol, maybe in an extreme case, but yes the motors around those years were known to blow spark plugs. Especially the 5.4 and 4.6 V8's. Not a common thing, but it did happen somewhat remotely frequently.

my 06 5.4 somehow loosened a plug, didn't blow it out but had a good quarter-half turn to tighten it!!!!!

I did some research and apparently it's a pretty expensive fix. also my rear end is shuddering In Reverse and when I accelerate in a turn any ideas on that?

Accelerate in a turn while in reverse? Or just when you take a turn while driving? And what gear ratio do you have in the back? And limited slip or non-limited slip?

It does it in reverse and then in drive when I'm turning out of somewhere it's the h9 355 rear end I just didn't know if that means my clutch paks have gone out or what

Ok so limited slip, what kind of shuddering are we talking about? Like your back end shakes? Your tires lockup or slip? A grinding or rubbing noise?

First. Raptor nailed the plug issue. I had to tighten one in 10 years. Have had plenty of coil probs. but never a plug prob. But mine is an 03. U said 02. 3v have more probs fer sure

Now your rear. Did u check the fluid level? How bout the axel seals? R they wet? Have u tried to change it? Diff cover gasket wet? I have a 9.75 sterling. 3.73 locker rear. Axel seals went. Pinion seals went. She doesn't do wheelies but she gits if u know what I mean. But that was why I had seal probs. check ur oil levels and leme know what u see

I have checked my fluid level I need to change the seal but my level was fine but as far as doing anything with it I'm in ohio working and Loretta (my truck) is at home in bama
