Thread: stock track rod - made of cheese or just me?

Try pushing with string!

urmmmmm its in tension when its pulling the wheel around one way and its under compression when its going the other... unless youve got some magic way of having the drag link and steering box change sides of the vehicle when you turn the wheel in differing directions...

Yep - not 11/16 x 20 . For anyone wanting to make their own steering rods, Brian's Taps are good quality and for a Bargain Price!!!

Dave - I can't see how you can say that a HD track rod damages a PAS box???

It seems to be only the LR community that believe vehicles should have engineered weak links (axles and steering rods) to protect the other components.

I have upgraded both my axles and my steering rods (as have many others) and it hasn't lead to any other compoinents being broken.

I am sure that the pi$$weak track rod was simply a LR engineering oversight, rather than an intended design feature.

look really closely you'll see that both the drag link and tie rod are made of the same bar stock.

if you slam a wheel on something hard the rod bends, dissapating the extra force into bending the rod.

in a nutshell putting a stronger rod in is like welding in re-enforments in the crumple zones of a modern car it works well preventing it from folding up when you have a gentle touch thats just enough to bend the panel but should you have a decent hit.........

The last box we had fail at work from this stripped the splines off of the steering box and fractured the drop arm and was admited to being caused by the driver slipping leftwards on a slope and into a large boulder while trying to catch the slide by steering left and accelerating.

If we still have the box and arm I'll get pics.

Well ive bent a few and now have reinforced ones on my truck and will be going to hollow bar 32mm od soon and i havent busted anyting and its had a few hard wacks in some large ruts all i can say is that if you've seen one damaged that bad it must have been a F@#$%^$ big hit tho ive seen how some of the mil spec rovers get treated

6x6 or 4x4?

That is a pretty impressive failure - never seen anyone manage to break a drop arm.

I've bent more track rods, than most people have owned Rovers, they are crud, you don't move the weak point, you eliminate it, Rover engineering sucked when it came to metalurgy, purists can disagree, but its fact
