Death wobbles on 80series
I keep experiencing death wobbles when i hit small pot holes on the road. I have checked the panhard bushes, had a wheel alingment, wheel balance. Im running 6in lift with 37's. Ive fitted snake racing drop and have checked they are the right ones for 6in lift. But im lost now because i still keep experiencing them. Any help would be much appreciated.
had a similar problem with a sierra. was a combination off pin bearings and wheel bearings. jack one side up stick a bar under the tyre for some leverage and give it a liftif there is some movment there you will feel it.
alo had a tyre with a bad belt in it that was causeing another sierra to do the same couldnt find the prob anywhere till bout a fortnight later when a bulge apeared on the tread was nearly a third the circumfrence of the tyre

IF IN DOUBT GO FLAT OUT
Wheel bearings, radius arm bushes, steering box adjustment, ball joints, king pin bearing plate shims (not sure if they are the same as nissan?)
Although I drive a Maverick (patrol), I find that the wheel bearings are usually the culprit. I give everything a once over every couple of months to be sure. Good luck, can be a tough one to find.

use to experience in mine from time to time but now i fixed it by mounting the steering damper in a different position and it drives perfect, but i am still going to do a full overhaul, new steering links etc http://www.youtube.com/watch?v=qCy6Ml3cj54

for the OP, if you have checked everything else, check the bushes in the Snake arms, they are well known to flog out quickly

[/b]Hi I have been chasing a wobble in my 80 as well. I think I have found mine. Pan hard bush on the diff wsas flogged out. Urethan was split. When we were checking everything it felt fine. Do your self a favour and pull off the panhard rod and physically inspect the bushes.
Photo of split bush
i wil be replacing both with factory bushes.
Hope this helps
Cheers Chris

it is unlikely to be the steering box. If it happens under brakes, check wheel bearings.
adjustment is done by loosening the locknit on th top of the steering box, use a large screw driver to adjust the pre-load srew, then tighten the lock nut.
steering wheel should have about 30mm of side to side slop/free play at the steering wheel.
if you overtighten the steering box preload, you will accelerate the wear/ also they tend to wear in the 'normal/straight ahead' position before they wear at full lock as this is wear most driving is done. If you tighten pre-load on the steering box in the straight ahead location, it can be too much pre-load at full lock
as 4runnernomore ofund, things can look OK, but a small amount of wear on something can be all it takes to start the problem, the bigger the tyres, the more likely it wiil show up.

Another thing that will cause death wobbles is bias belted tyres in cold weather. Left sitting overnight, they get a big flatspot on the bottom. I checked everything in my front end and it would still do it in the morning. I threw on the Big Horns and fixed!

bias ply tires went out in the 70s. Can't understand anyone still making them?BadMav wrote:Another thing that will cause death wobbles is bias belted tyres in cold weather.

The worst part about being told you have Alzheimer's, is that it doesn't just happen once.
