Is the death wobble I've read about a constant wobble at a specified speed (looks like 45mphish)?

If so I have a different wobble. When I hit a bump at speed sometimes it'll turn my steering to whichever front wheel the bump hit. Now on a rare occasion, I'm unsure of what kind of bump or how to replicate it but I did have a time where it hit a bump and then I was still traveling straight but the steering wheel wobbled left and right a few times thus shaking the truck around.

I believe this may be my steering damper but am unsure at this time.
It might be the original one. I replaced the shocks last year.
It's a 2003 Disco II just shy of 150k miles.

 

Jack the front of your truck up with both tires off the ground then get in there are start moving the tires around or get someone to shake the steering wheel. you'll probably find that your tie-rod ends, steering dampener or maybe your drag links are worn on one or both ends. It's an easy fix and can be done with basic tools in your drivway.

If you can handle the wait then order this stuff online. It's usually less than half what you'll pay from the dealer.

 

I can definitely handle the wait. I don't mind.
If I mess with the tie rods I'd need an alignment right? If so I'll hold off on the new tires.

 

yep, good idea to get alignmemt

 

if you hit a good pot hole while taking and off ramp you will wish you spent the $30 on a tie rod end, it will cost you more than that to get the skid mark removed from your seat.

 

Sounds like you have two problems. A bad jerk to the steering wheel when hitting something with just one front wheel can be worse if your steering damper is worn.

The wobble back and forth is not caused by a weak damper. That's caused by suspension bushing and/or ball-joint (meaning steering upper and lower ball joints and/or tie-rod ball joints) wear.

Fix the back and forth wobble first, then your damper. If you do it in reverse order the damper will mask the wobble issue.

 

Check the nut on your pitman arm. I bent the locking washer back on mine and it was finger tight. Should be 178 ft/lbs.

 

You can use the checklist here:

Instead of swivel pin preload, you'd need to check your upper and lower ball joints.
Also, AFAIK, there's no check for loose hub bearings on a DII.

 

Yeah, could be pitman.
I had this exact problem in a Discovery I.
Problem was engine oil was rotting the PAN HARD bearings.
You need to put in Poly Pan Hard bearings.
Once you fix those - no wobble.
Pan hard bearings will affect the steering and replacing them has the greatest positive effect on the steering.

 

I don't believe there are bearings in the panhard rod.
They'll only have the greatest positive effect on steering if they are the problem.

OP, don't just start throwing parts at a problem. Diagnose it to find the source of the problem, then repair as needed.
