Yet more issues...

[Evo]

Hey guys,

After a bit of a trouble free patch, I had a bit of a grinding rumble from front wheels, and noticed swivel hub was leaking.
Got it all checked out and wheel bearings were on their way out (left front was pretty chewed).
So, got swivel hubs overhauled, new front and rear wheel bearings.

After getting it back, bad steering shake, and an up/down vibration at 80km/h plus, both of which weren't there before the bearing and swivel hub work.
There was slight steering shake, but definitely something I could live with, unlike now.

Question is, what could be causing it all? Drives fine under 80km/h.

Took it back and they said balance could be out, so balanced the wheels.

Still there...

Just FYI, 1998 GU 4500 Wagon.
25000 (if that) kms on tyres (rotated and balanced every 10000)
10000 (probably less) kms on suspension (all suspension)
100 kms on new wheel bearings (front and rear) and overhauled swivel hubs

But like I said, issue has only appeared after last lot of work, so wheel bearings and swivel hub overhaul...

Getting very short on money and patience, even thinking of selling it because it seems to be never ending, and mostly when I've just dropped a heap of money on maintenance/replacements...

Any information is much appreciated.

There's a shim for the kingpin bearings that could have been left out when being put back together. That shim has been known to effect wobble in the front end......

Leaving a shim out won't affect it as it'll pre load bearings more.

I'd take the locking caps off and re check bearing tension, maybe just need a nip up now they have seated.

Did you get an alignment done after the rebuild?

Jack it up and see if theres any play in the bearings, does it shudder under brakes??

X3 with above posts... the first thing to check is the last thing that was touched so I'd check the bearing preloads before setting the Car on fire to get the insurance money

Hey guys,

Thanks for the replies.

The guys who did it said it was put back together with everything that came off (except for the replacement new components).
As for bearings, I'm not sure how to check and/or adjust. And no, was told alignment wasn't needed...
No shudder under brakes.
Might try to jack up the front tomorrow and see if there's any play anywhere.
At a steady 100km/h there's still the up/down thing, almost like a tyre has gone out of round, but all tyres have been checked and are good...
It's just so frustrating because it seems every time I dump a heap of hard saved coin to get something fixed, I end up with some form of side effect issue that ends up haunting me for weeks to months before being found...

welcome to owning a 4wd.....................

mind you, if he (the guy who did the work) said everything went back together as before (but with new parts) I would be asking to explain how it never had the wobbles and now does......... after he has touched it

and if he says "oh thats the Nissan Wobbles" punch him in the nose and say - "thats for lying".......


I would also be looking for a new Mechanic - if everytime you take it to him it ends up costing way more than it needs..... something fishy in Denmark.........

I've had 4x4's in the past, but never having so many issues like this...

As for the work, the bearings and swivel overhaul were the only things this mechanic has done on the GU.

This is what makes me feel like getting rid of it, because no matter what I do, where I go, I have issues, and end up chasing them...

Only a minor isssue EVO, if you jack it up and find even a small amount of play by grabbing the wheel top and bottom take it back.
If no play is found take it back anyway and request he check his work as the "problem" was not there before, be firm

[Evo]

Seems to be the plan.

From my understanding, wheel bearings, swivel bearings, would cause steering shake, but what about the vertical vibration I'm getting at 100km/h?
Still be related to the same components?
Or would the new parts have caused a pre-existing issue to become more apparent?
