    K&N Air Filter

    Spent 20 minutes searching, can't believe no one has asked this question. Alright folks, is the K&N air filter overrated in a stock setup? https://www.knfilters.com/ford/expedition/5.4l-v8-gas/2006/ I would prefer to order the FoMoCo parts, but I had an F150 a loooong time ago where the...

    4wd binds, front axle doesn't engage

    You are awesome, Ham. Thank you for the quick, knowledgeable reply. I had to wait for the weather to clear to try reproducing the problem. In all honesty, I had not tried to engage the 4hi/lo in over a year. So I went out today to capture some video and pictures for this post and found that I...

    4wd binds, front axle doesn't engage

    2006 XLT 5.4 V8 I've had this expy for 10+ years. 4 hi / low has never worked. Front axle won't engage. A 4wd guy diagnosed it while it was in for other work a long time ago. Said it was an electronic box that was bad. Some thing that mounts on the front axle itself. I'd like to take a stab at...

    2006 XLT 125k Timing Chains

    Well I appreciate the knowledge. Maybe some day I will meet an independent I can actually trust so I can start saving some money!

    2006 XLT 125k Timing Chains

    Just an update to close the thread. I paid $3600 to Elk Grove Ford to do the rails, guides, chains, phasers, both solenoids, and all the other related crap. The motor had 155k miles on it, and I have to say that it feels like a brand new engine. It is very responsive to throttle input, and my...

    2006 XLT 125k Timing Chains

    Thanks John. Plugs are good (< 25k mi.) for now. I'm researching the need to replace cam phasers. Any advice is welcome.

    2006 XLT 125k Timing Chains

    Thanks. I've decided to take it to the dealer and get it all taken care of. This will set me back, but Lord knows I can't afford the alternative -- a dead Expedition.

    2006 XLT 125k Timing Chains

    Thanks for the replies! Really appreciate it. To be honest the tech says the chains are noisy, and that's literally it. I am not trained enough to know what a noisy chain sounds like. I've left a message to get details on what the $3,500 includes (cam phasers, guides, etc.). Like you all said...

    2006 XLT 125k Timing Chains

    Hi, my name is Mike. My family has a 2006 Expy XLT approaching 125k miles. Original everything except plugs @ 100k. I service it regularly at my dealer (sue me, I love them). The last time it was in for service, the tech noted some noise from the timing chains. I have read on social media that...
