Off-road maintenance

[DjMojon]

I’m new to off-roading but have definitely been taking advantage of the Bronco’s capabilities. I’m approaching 30k miles and probably go on some moderate trails about every other month. What general maintenance things should I be considering? What bolts need to be checked/tightened to avoid any failures on the trails

Pull the skid plates and take a good look for possible leaks, loose wiring, torn boots, etc. & clean out any debris that will build up over time.

EDIT: Don't pull the gas tank skid as it supports the gas tank.

Honestly... most of it is identical to the typical maintenance you'd normally do.

The only real difference is you may want to speed up the maintenance schedule on a few items. Similar, in many ways, to what you'd do for pickups that tow/haul frequently, or for vehicles that operate in extreme conditions.

Areas of interest:

• Transfer case fluid
• Front drive unit fluid
• Rear differential fluid
• Transmission fluid
• Air filter
• Suspension
• Sway-bar disconnect

The first four items have 150,000 mile service intervals "by the book". A lot of people like to speed it up anyway, but definitely something to consider if you are off-roading frequently.

Air filter has a 30,000 service interval, but if you are off-roading in dusty environments or frequently water fording, it makes sense to speed that up. Personally, I do yearly changes on the air filter when summer hits regardless of mileage. Pollen season is just horrific up here, so bad that the air filter changes color by the time spring ends.

The suspension is more just a visual check to make sure everything is in place and there are no struts leaking. This something people should be during oil changes anyway, but frankly a lot of people don't. I like to put eyes on everything before I leave for a trip.

Sway-bar disconnect is just a check for fluid leaks and whatnot. It is a closed unit that shouldn't need service, but obviously if it's leaking you'll want to be aware of it. This really just goes to what @PWillette was saying... take off the plates and give everything a good clean/inspection every so often.

Boots - Check tie rod & CV boots frequently.
They're easier to tear than you think & a failure can get expensive.

I tore a Tie Rod boot while on a rally event & ended up needing a new steering rack.

Air Filter - Check it after every day on the trails. It take 10 minutes & even just checking it & blowing it out with an air nozzle is good PM. Change it more frequently than you think. It's like $15.

Fluids - Change the Diff & T-Case more frequently than reccomended. If you're really using yours off-raad, I'd do it at 25-30k. And use good stuff.
I used all Amsoil & I think it was like $120 for the fluids & took me like an hour. Get the squeeze pouches.

Bolts - do a simple bolt check while you're under there. Would suck to have a breakdown because something worked loosed & you simply didn't notice it. I'd say do this before a major day of offroading.
