We all look for ways to make our Jeep's
better, stronger and more reliable on the trail. Each time a part fails when
we are miles into the boonies and our favorite part stores are distant
memories, we rack our brains to think of ways to keep it from happening again.
This is just such a tale of woe and the easy and cheap solution I found:
During a trip out to the Rubicon I decided to try the
Little Sluice. At that time the Wrangler had 35" tires, 4" of
suspension lift and 4:10 gears & a rear locker. I thought I was prepared,
but the dismal 38:1 crawl ratio quickly made the ride through the sluice seem
like a series of poorly controlled crashes. I beamed with pride at the end as
I thought I had made it out without any serious damage. I was wrong.
Among other undercarraige bits that were well pounded on
the Sierra granite I had managed to whack my draglink. This is the steel tube
that connects the pitman arm on the steering box to the steering tierod. I did
not notice it much at first, but some time later just before hitting the trail
that runs down to Buck Island Lake I had to make an extremely sharp left and
then right turn through a tight rock obstacle.
I
turned the wheel all the way to the left just fine, but as I turned it all the
way back to the right something funny was happening.
Even though I turned the steering wheel to the far right
my tires seemed to stay cocked all the way over to the far left. I had
pretzeled my normally straight tie rod into a neat L-shape. The slight bend it
had received in the Little Sluice had weakened it enough to allow it to bend
under stress.
Luckily
I had an underhood welding system. In over a year since had been installed I
had never had a chance to use it in the field - but now it was to prove itself
invaluable as we straightened the rod out (sort of) with hammers, bashing
against boulders and plenty of manly grunts.
We then welded a scavenged piece of angle
iron to it for reinforcement (this fix performed well for over a month).

This is the field fixed draglink installed in the JeepThe aftermath of this incident left me
wondering how to keep this from happening again. After all, no steering makes
trail work much tougher. Chrome Moly Tie Rods are available, but they are
expensive and while stronger than mild grades of cold rolled steel CrMo is
more brittle and tougher to weld or repair in the field.
It did not take much in the way of genius
to figure out that filling up the drag link's hollow tube would make it much
stronger and more resistant to bending. I made some measurements and found
that the internal diameter of the tube was exactly 5/8".
A trip to the local hardware store (OSH)
netted me a short length of 5/8" OD cold rolled & hardened steel rod
for about $8. I cut this to length (allowing some space for the tie rod end
adjustment) and painted it to inhibit rusting. I then removed one tie rod end
and drove the rod into the drag link tube. The fit was so tight that most of
the paint came back off as the rod slipped into the tube.

So - for a measly $8 and about 20 minutes
of work I managed to make the drag link probably 3 or 4 times stronger than it
was before without any chance of weakening it by welding something to the
outside.

The only worry now is that some other
component of the steering system may be the "weak link", but
gradually all of the links will be better and stronger and more able to
survive the rigors of the toughest trails (saving those long walks). After all
- if I wanted to hike the Rubicon trail, I would not have brought a Jeep!
