Post by **narns1mav** » Wed Mar 05, 2008 10:37 pm

i have a gq lwb 6 inch susp 34 jt2

all was fine went bush the other day

now it has a bad shake through the steering wheel at about 60 km - 70km after that it goes away

also just fitted after the trip

new panhard bushes front gen nissan

new hd tie rod ( from wheel to wheel ) also with new tierod ends

also disconnected the tough dog rtc damp

also sold the 34's
and the second hand split rims ive got for the moment still do it
now ive got 35et and they still do it

the whole lift is about 1 year old

inculded was new
shocks
springs
caster plates
adj panhards
tough dog rtc steer damp

also has been doin this for about 2 months

sometimes when i go around corners there is a knock / clunk sound

and i can feel it through the drivers floor

also sometimes happens when goin straight after say going through a river crtossing

any ideas would be great

wow search for a start however ...

lift u have usually produces at least some vibe at front... (read death wobbles) some at 80 81.4 82 87 etc

however ...

replace EVERY bush try go rubber instead of Poly.

re-tighten every bolt on casters ...

could also be pinion bearings

also disconnected the tough dog rtc damp
why would this effect anything???

sometimes when i go around corners there is a knock / clunk sound

loose shock mounts? Havn't tightened bolts as required? Wheel bearings?

Are shocks matched to lift ie. if coils drop what is holding them the shock only????

be a bit more specific

i have read over 20 different posts

the radius arms have the nolathane bushes
so i mite change them

some one said the rtc may be the reason so i gave it a try

yes the shocks are matched to lift

Ensure all wheels are balanced, and have not moved or lost any balancers while out bush

check wheel bearings and swivel bearings for excessive play.

check steering box bolts are tight, and check chassis for cracking near the box.

check your panhards are tight?

i just found my front one to be loose, i fitted it, so fuck knows how its come loose, and id been getting a vibration at 80km on 31s or aroudn 73 on my 35s' so the same physical speed even though everything in the driveline is moving at a different pace.

tightened it up, and it seemed to not vobrate anymore, sometimes it can be simple stuff

your tyres balanced properly? mine do that at 80 through to 85 and it is the tyre balance

Post by **love ke70** » Thu Mar 06, 2008 8:30 pm

does it at the same speed with 3 different sets of tyres, and doesnt seem to do it now ive tightened the panhard, ill see how it goes with a bit more driving.

i did wonder tyres being out of balance, but swapping sets frequently and never putting them back on the same corner kind of eliminated that possibility...

cheers

Mate had the same problem at the same speeds

I just had my tires balanced today and it seems to have gone away but i will update you tomorrow and tell you how they go on the way to and from work tomorrow

yep, that's how mine started out. give it 6-12 months and it will really get the death wobbles and balancing tyres won't help. At early stages, slightly out of balance tyres can set it off, but that doesn't mean its the cause of the actual problem. Mine got to the point where it was totally undriveable after crossing a flooded cause-way - indicating a problem with bushes. In my case the panhard rod bushes.

has slowed my death wobbles they are much less violent now but i will check out all my bushes out soon

UPDATE

i have now done the rear panhard bushes and fitted drop boxes and the radius arm bushes ( genuine nissan )

also have checked wheel bearings / swivel hubs bearings and they r fine

and it still does it any other ideas i was told maybe a bent diff ?

The clunk in the floor is likely to be body mounts - does it get worse in the wet?
