Offroad-Express

OK well on a quick mission down to the river I hit a bump and was a loud bang,that was fine, there was no 4wding just gravelroad. Further down the road it started to develop a rather large vibration. driving home it steadily got worse and worse.on futher inspection the cross member is bent but everything else is fine will post pics and check engine mounts and gearbox mounts in the morning.

any idears what it could be?

cheers sam

Umm what crossmember?

the gearbox cross member

sorry in a surf ln130

Id be checking the mounts man, pretty hard to tell from here aye. Theres no puddles of oil or anything under it yeah?

steerin arms ok? wheel shimmy? can ya explain the vibration a tad more? wheel shimmy? only when drivin? when sittin still idling?

gotta be asked, how the hell you hit somethin big and hard enough to bend a cross member but not collect a diff etc, or see it prior!!?

just lay under there and locate the vibration.. you'll get there..

I just did a three point turn and collected something as I drove back onto the track it's like siting in a massaging chair it does it whilst the engine is on faster you go the worse it gets @ 100 it's so loud you can't even talk to your passenger

Driveshaft

checked that no dents or anything on it

checked the uni's?

happens while engine is on.. you mean idling it happens or only when ya drive?

the whole time the engine is on and had a quick look they look ok

Check EXHAUST. FITZY.

^^^ what he said
aslo check your rear gearbox mount , engine mounts and that your transfer case skid plate is not mashed into your transfer case.

EXHAUST mounts? and the transfer bash plate is fine i just brought a new crossmember so ill throw that on and see what happens.

on futher inspection i found this

any one?

if no ones has a clue can some one point me in the direction of GOOD mechanic in chch that doesnt charge a fortune?

that oil leakin from your diff housing front pinion would be from lack of a goody one of these..


so in order to do one of those, just follow this link.. http://www.autozone.com/autozone/repair ... 52800611d5

that wont be the cause of ya shimmy unless ya really crunched ya front pinion, then ya should be able to get under there and wobble it around relatively easily...? tried that?

yes Rick at 4wd accessories nib's knows where he is now

on the sockburn roundabout side of watts road. about 2 or 3 driveways from blenhiem road end...

Hi Sam,
i'm with Fitzy's opinion on the exhaust, if it's doing it when the motor is at idle (vehicle not moving) it's most likely to be your exhaust hitting body/chassis somewhere.
I'm home on Wed if you want to drop in I can have a quick look, but Rick@ 4wdacc won't rip you off.....34 Watts rd

sweet hes just around the road from were I live with the amount of oil ive droped i dont think that it would be a good idear to drive so might not be able to pop out thanks any way tim

just brought a new cross member 20 buxs not to bad and ill talk to rick and see what he thinks thanks for all your help guys

ok so my front diff was fffffffffdd any way so im just going to buy a new front diff i see they are about 200 buxs on trade me anyone know were else to look and how hard they are to change?

found out what the large vibration was the gearbox was hitting the bodey of the truck i managed to push it up.

the rear diff i got to have a look at it i want to put a lsd or lokka into it any way so i dont know.

why put a lokka or lsd in ya daily driver if ya wantin to keep it in good order and use a dedicated offroader?
sounds like ya must have taken a massive punt in order to fawk the crossmember to do that.. ruff carnt.
