TJ 4 link front - Pirate4x4.Com : 4x4 and Off-Road Forum

FireTruck · 06-26-2002, 12:17 AM

I am in the middle of triangulating my front on my TJ... rear is done and seems to work no probs. Lower arms run on the outside of the frame rails, upper arms triangulated to the inside.

Front is all over the place... some strange vibes etc. Don't have any pics at the moment. Clears everything fine, articulates like crazy.

Anyone triangulated the front of a TJ got any pics/links/info I can check out?

The IT guys here at work are a bunch of friggin monkeys, and everytime I try to search my pc crashes. Damn honda drivers.

I am thinking it's allways going to drive fucked up.

Think about the way it used to be, as the axle dropped the track bar forced it to swing in an arch that was very close to the arch the draglink made as the axle drooped. Now your front axle will travel straight up and down but your draglink still runs the same arch (unless you have full hydro steering) so when the axle droops your steering wheel should make a hard right just to keep going straight.

Are you running full hydro steering???

try throwing on a longer panhard bar.

Ya, without the track bar, you want to make your steering as much like a leaf sprung front as possible. Get the drag link as close to horizontal as you can to minimize bump steer.

No full hydro steering... I know there will always be some bump steer with this setup, but as long is it is not too bad I can live with it.

Drag link is not too bad, but still has a bit of angle to it.

Have a few things to try... tightening up the bushings and joints, hardening up the shocks (I think they are set too soft), putting some round tires on (those flat spots make it hard to know what is going on), and working with the steering stabilizer.

Will see how this goes.

Just wunder'en how you mounted your front links??
Did you mod the exhaust @ that 1st corner??
Mount under Or inside of the frame??
Thanks

Will post some pics when I get it sorted...

No exhaust at the moment... it will be slightly re-routed. Upper arms inside the frame, lowers outside/under.
