Trail Hacks: Recent 4x4 Fixes That Got Us Back to Camp

Aug. 18, 2016 By Justin Fort, with photos by Dustin Dailey, Majid Gol and Justin Fort

Broken parts happen. You can fix them. Broken parts happen more often when you’re four-wheeling. On-trail fixes are harder: got tools, got parts, got lighting? No garage, no creeper, no parts store. Can you be prepared?

During a weeklong run through the awesomer parts of southwestern Colorado’s off-roading territories, we broke some parts – or tried to. Then we fixed them. While we were prepared to deal with some breakage, other bits, not so much. However, you can avoid some trailside freakouts with a little preparation and vision.

When you’re off-roading, what’s onboard?
- Tools? You might not be ready to rebuild a diff (or are you?), but an assortment of the usual suspects can fix a lot: popular sockets and combo wrenches, a few pointy pry/screwdriverlike objects, some snips, some pliers, a crowbar, a hammer or two, a knife, a hacksaw, a few pieces of wood to hammer on, safety glasses, a funnel, a pair of gloves.
- Work lights? A few AAA-powered LED bars or a 12-volt droplight go a long way.
- Achy breaky parts? Does your truck murder bushings? Is there a power-steering line that blows? Do you have bolts that rattle out? What about grease? Fuses? Fluids?
- “Temporary” fixes? Zip-ties, duct or gaffer’s tape. 10/12-gauge copper wire or some wire hangars. Stranded automotive wire. Spare nuts, bolts and screws, with lots of washers. Hose clamps. Loctite.

Ahhhh, OE locking hubs on a Dana 30. To upgrade, or to upgrade? Only the driver’s side bolts were walking out of the hub; as of yet, we don’t know why.

Corporate Five-Bolt Locking Hub Bolts on a Dana 30
Sooooo, what’s stronger than Loctite Red? While the five jailbird bolts holding the manual hubs together on this Dana 30 have been a flight risk for months, they were reinstalled with copious No. 263, and by all appearances we’d solved the half-day loosening issue. Or not.

Cursing red Loctite while installing hardware store bolts parked in front of a church wearing flip-flops. Some part of that has got to be a sin.

We found this handy instructional graphic for the different types of Loctite (courtesy of the Henkel Adhesives blog), and in case you’re interested, there is a wicking Loctite. Awesome.

After a day on-trail, rolling both the lumpy Kendall Mountain climb and historically rock-infested Engineer Pass, four of five bolts had departed for greener pastures (or some pastoral trailside nook). Hmmm, probably should’a checked them. If you’ve got a problem bolt, keep a few in the truck. Or a few dozen. In this case, we got lucky and Silverton’s hardware store (it’s for sale!) had a strong selection of bolts, including the type we needed. Should another dose of thread-locker not do the job (perhaps the new Loctite “Black Hold” will be enough), there’s always the old trucker’s trick of drilling and wiring each bolt head in series, or the installation of some Jeep-sized nut indicators.

Despite missing the left-right alignment of the gaffer’s tape, the stuff didn’t budge, and is still on there after three more days four-wheeling, plus the drive home.

4Runner Anti-Roll Bar Bushings (Front & Rear)
Having shredded these bushings in both the front of the truck and in back, one would be inclined to brand the axle-mounted (rear) and frame-mounted (front) “sway” bar bushings on a third-gen 4Runner a wear item. One would be right to do so. The anti-roll bars act in a partially limiting capacity at full droop for this platform, and those bushings take a beating.

While we were prepared with a backup front bushing, the departure of the rear bushing was a surprise – three front bushings had failed but never one in the back. Fortunately, the high-steel clanking of the bar-on-axle tube was readily discerned. A homefab stand-in bushing of plastic gaffer’s tape (think of the tape used to bond a carpet’s edge to cement floors in a convention center) was made by wrapping the tape around the anti-roll bar to the bushing’s thickness. Ironically (or coincidentally), we hadn’t packed any tape originally (duct tape would have worked too) until being chided into doing so at the last minute. Thanks, dude.

Super Bronco Crawler Guy (a yearlong Silverton resident – how cool is that?) stopped to help diagnose the blown power-steering line on the Renegade. We pulled the belt and limped it back to the cabin.

GM Power-Steering Pressure Line
The CJ-7 Renegade in our group was a small-blocked restomod that was still shaking out some cobwebs and flaws. One of the things that had been... underdesigned... was a problematic power-steering hose: a return-pressure hose (the “suck” hose) had been used on the pressure side of the power steering pump (the “push” side). Apparently, there is a difference.

Bob from Bob’s Truck Parts & Hoses in Durango not only knew what hose was necessary, he had a machine to build them (and another machine to pressure-test) in-house.

During high-twist ‘froading moments, the steering pump overloaded the lower-strength line and popped it at the fitting. These parts had divorced before, but another low-pressure hose was put back in place of the previously blown line (not realizing that it was the wrong line altogether). On-trail a half-hour out of Silverton, the low-pressure line blew again, so limping back wasn’t much trouble.  This was good, because there was no spare.  Instead, we slipped off the power-steering pump belt and arm-wrestled the truck home. A proper replacement was found in nearby Durango – a hard-working farm and trucking town – with a truck mechanic named Bob at Bob’s Truck Parts & Hoses. Bob made a new line out of 4000psi Gates SAE 100R2 (mmmmight be enough). Next time, a $40 spare will be in the bits box.

The magic shock-proof zip-tie. The FJ’s owner was so awesome he didn’t even stop to trim it, and yes, this was after almost a week of off-roading.

Dearly Departed Lower Shock Bolt on Live-Axle FJ Cruiser
This one was worth a laugh and about three beers. After days of ‘froading, the lower bolt holding the port shock absorber to the axle of a late-model FJ Cruiser shook itself out, and its replacement – a relatively undersized black zip-tie of unknown manufacture – kept the shock in place for the rest of the week on-trail and, like the little piggies do, all the way home.

A simple fix: a tiny new hole and a zip-tie succeeded where pop fitting after pop fitting had mysteriously departed. We’ll leave it and report back if it ever fails.

While the wisdom of having zip-ties along for any trucklike adventures is indefatigable, the logic of one enduring this sort of load may surprise you. A well-balanced suspension component (such as one that would be designed by a Toyota engineer) puts relatively little stress on a shock, especially in low-speed settings like on-trail (it doesn’t hurt if your shocks are blown...). In fact, your author has four-wheeled with just one shock damping the whole rear axle after grenading the driver’s side rear shock (seriously, it exploded). The less there is to dampen, the less stress there is on that shock-to-axle connection, and as in this case, one lone zip-tie was sufficient.

Flapping and Flopping Plastic Panels #1 and #2
With mods come changes to parts, and changed parts occasionally interfere with original equipment. With the removal of OEM 4Runner bumpers and their replacement with high-clearance tube/plate bumpers, more air than originally intended flows into the engine bay, and in turn, causes several plastic wheel-well panels to puff into the wells. This wouldn’t be a big deal, but the upsized Nitto knobbies used on the truck for off-roading take up more wheel-well space and rub against those pillowing panels. Whoops.

What do you mean you don’t keep a jar of worn out reciprocating saw blades on your workbench? You’re clearly not doing enough sawing. We drove it in like a nail, and someday we’ll paint it black.

Around town, the rubber-on-plastic interference was a case of misdemeanor battery, but at freeway speeds through the southwestern desert, these plastics deformed enough that the tires began commiting felony cannibalism. A zip-tie – from the cluster of that we keep strapped to the rollbar (credit where credit’s due: we saw that trick on Dave Collier’s Gnarly Racing pleasure juggy) – pulled the well liner back, and a leftover reciprocating saw blade pinned the master cylinder shroud in place where no plastic pop fitting could cope. Never be afraid to repurpose good chunks of metal like a Sawzall-style blade – name brand ones are sturdy and have a lot of uses even after the teeth are dulled (though the bimetal blades are tricky to weld).
