steering stabilizer broken???

Funny you meantion that. At Vic winch Dad bent his drag link and snapped his steering stabilizer in half. We straightened out the drag link but couldn't borrow a steering stabilizer. So Dad had to drive home from Warragul to Box Hill with no stabilizer, and had zero wobbles or shimmy ( He had a slight wobble at 70-80kmh on the way down). This is an 89 Patrol running 35 BFG Muds on Toyota offsset 15x8s.

Weird eh.

stabiliser isnt really all that necessary and is really only to stop major shunts to your steering, ie potholes and stuff.

[Mousie]

just got off the phone with 1 of my mates he reccons that the wheels need to be rebalanced he had the same problem

got the wheels balanced and problem solved

i have no weights on my passanger wheel amymore i just seen but i didnt know weather this could cause that mutch of an issue

[ozy1]

balancew can also be an issue, get them done and report back,
also check Panhard bushes, are they rubber or nolethane(or whatever) as they can wear out quick at times, factory rubber is a better option,

[MKPatrolGuy]

Even the diagonal expansion joins on the Freeway bridges, driven over at 110kmh, didn't cause a prob. He is still driving without it because he is chasing up if you can get a replacement damper for the RTC stabilizers because the one he busted was only 1 month old

[Mousie]

ok cheaked out all my stearing/suspention bushes there all like new nothing rong with them at all.

tho my passanger side has no weights on the tyre and all the others have about 60g of weights
doupt this is enough to cause this issue

its odd tho i`ll be driving allong then all of a sudden shakes REALY violent around 80km/h and i have to stop then go again
dostn happen all the time tho..
only sometimes. its rare .
but i would hate for it to happen at 110 down the freeway.

will get wheels balanced tomorro and see how it goes but yeh its a realy odd thing i carnt see any issues with bushes anyware.

could the power stearing pump have sumthing to do with this? it is leaking ever so slowly.

This has been done to death in the Nissan section. Very common problem. I've fixed mine in various ways each time it arises. Last time was invisibly loose u-bolts.

[Mousie]

were are the U bolts ?

i have cheaked castor its all rite.
bushes - good
shockeys - good
tie rod ends - good

first things first, get your wheels ballanced, GQs are proce to wobbles caused by wheel ballance issues, and sometimes they will need to be dome at a truck place on the vehicle. depending on the tyres you are runniong it may be worth getting them tab ballanced. ACE tyres at smithfeild are the best for this, they cost arounf $60.00 per wheel fo this though.

The chances are this will ix our death woble isue, particulaly if you have checked bushes etc, but generally bushed will not be as bad wobble wise as out of ballance tyres.

If tyres are not the issue, check all the rod ends etc and bushed and failing that and dependng on lift you may need to look at drop boxes or arms.

if the wobbles are minor it could be bump steer and you would need to check the steering dampner and mayne look to a HD RTC type dampner

[dirtyGQ]

big chunks of mud can make it wobble like hell too

yes so check the rim, and if you have poped a bead you may have mud on the inside throwing it out of ballance

Its your tires are they healed and toed at all?

[bilby]

were are the U bolts ?

i have cheaked castor its all rite.
bushes - good
shockeys - good
tie rod ends - good

u aint got any its coil sprung

u bolts are for leaf springs

[Mousie]

ok got the tyres balanced same fucking problem

what is TAB ballanced?

i have looked at the nissan bible about this and seems always points back to bushes

[HJ60_HEATHUS]

is the front end running, ie hubs lockeD? might be something stupid like loose drive shaft bolts (hey, it happened to me )

[Mousie]

hubs arnt locked in... whitch drive shaft bolts are you talking about?

if u have no C clamps on your axels holdering the inner part of your hubs back could they engage ?

also wats the point of that C clip

[zooki]

Sierras do it all the time, its a harmonic vibration.

check your steering Stabiliser and swivel seals

[dwaynes]

well i had this and it drove me crazy couldn't work it out tried everything.

i need to change the brake pads and in doing so found some caked on mud hidden in and around the brake caliper changed the pads cleaned the mud no wobble since.


could be something to look at

[Mousie]

ok were are they at?
