90km/hr Vibration - CV Inner/Outer
Re: 90km/hr Vibration - CV Inner/Outer
geez geeves you make it sound so easy - I'll have a crack this weekend if the weather is good.
Re: 90km/hr Vibration - CV Inner/Outer
no harder than an oil filter although it will take longer. Whos pressing the bearing on for you?
Re: 90km/hr Vibration - CV Inner/Outer
Haven't sourced anyone else but isuzu - Do you have someone in mind geeves?
Had to have photographic memory for pulling apart the brake assy - fortunately I also read the bit in the manual stating the hand brake lever was on the inside too so was able to put things back in place after. Anyways time would only allow me to pull apart the rear RHS to check things out - why I didn't do the LHS first i dunno. So shifted the 1/2 shaft out and it appeared to be ok- it wasn't bent, the splines weren't worn and there was no water or signs of rust. There was some clear oil inside where the hub slides into the axle housing and I can only guess it came from the wheel bearing? there was maybe a 1mm gap or less between the retainer and the wheel bearing when I swung off the shaft from side to side. The bearing ran smooth when spun and showed no signs of play internally. So yep seemed a simple task to remove and replace. Once I 've pulled andinspected the LHS, I'll cut the retainers off and send both 1/2 shafts in to get the bearing replaced. hopefully that'll be cheaper.

So got the LH rear 1/2 shaft out and it was very easy.
Many thanx geeves for the method for pulling apart seems so ez now - could have done it in 30mins if I'd realised the handbrake was still on.
Pulled the 1/2 shaft and out came abit of diff oil too. Reading www sites suggest the breather line for the diff was blocked - sure was, the wee elbow and cap was blocked and the hose was clear so just pointed the hose to the ground and cable tied to brake line bracket ensuring nothing could drain back into the diff. Seems the elbow is rusted out.
The wheel bearing clearly has some play - much much more than the RHS. Shaft and splines were all good.
Got priced for the collars at $75 each from Waikatobearings better than $135.

Re: 90km/hr Vibration - CV Inner/Outer
WHOA - i've just realised my mistake with the breather hose better send it up!!! and maybe add more in case I do go water crossing and forget all about it.
Re: 90km/hr Vibration - still there
Got diff oil on the RHS now after the change to the breather hose??
The rear wheel bearings got replaced by Hydratech Engineering for $80 for both incl fitting replacement bearings and seals.
Got done in half a day by Brad and they got a 30 or 40ton press so no wonder he made it sound so ez.
Just gotta finda a tool to pull the seals out of the axle b4 they thin out my oil in the new bearings.
Not much difference in the old bearings but one every now and then with a bit of downwards pressure a lump is felt. I think the rear RHS is still good so might save it.
I had tried cutting the collars out with a dremel but couldn't get to the inside housing to finish it off. Didn't need to, Brad's shop had the press to do it.
The collars for $70 each from Gil at Waikato Bearings and lucky he's a good guy cos I must've dropped the rear brake pinsx2 and he sends me an email asking if I had lost any - yup must've flipped the shaft on its end and they fell out - cheers Gil for not throwing them out.
Any way Vibration still present but not as bad - it creeps in at 90 and almost gone at 100kph. When I'm slowing down its shakes more coming down to 90kph.
Feels much better though.....so one more wheel bearing to go....Front RHS.
And then a redo on the wheel balance and alignment asking to focus on out of round tyre or wheel this time @ HN Speedy and Lube - suggested by a good mate at Allquip.

Re: 90km/hr Vibration Update
Well all wheel bearings replaced vibration still exists - swapped front tyres with rear and vibration still the same at 90kmhr. Front RH bearing was buggered and purple from heat. I wonder what next.
Re: 90km/hr Vibration - CV Inner/Outer
can you describe the vibration in detail.
We are now looking at unusual things
A stone caught between the body can cause all sorts of vibrations as it transmits those normal vibrations from the chassis past the rubber mounts to the body. A bent side step will do the same thing
A broken or missing exhaust bracket also does the same.
A buckled wheel can do strange things. Swapping a set of rims with a friend is the only way to check this
Some mud tyres vibrate esspecially if the pressure is wrong
Gearbox and engine faults can cause vibration
Some vibrations are normal

Re: 90km/hr Vibration - CV Inner/Outer
Ok vibration appears to be at the front - and since the RH front wheel bearing was clearly the worst I suspect that is the area.
I do believe the hi kms travelled recently made the bearings appear purplish from the heat.
The front vibrates left and right and increases in speed as vehicle speed increases until its a shimmer. Noticeable on a smooth road but hard to find in Hamilton.
The front bullbar starts swinging L & R too and its in time with the vibration. The driver seat doesn't vibrate as much but gives me a nice tickle.
When driving beside a median barrier the shimmer is audible with the drivers window down. The passenger side - nothing.
The front auto hubs are unlocked since the front cv' aren't moving in rear 2wd and I could spin the RH Front hub without spinning the CV axle.
Could it be the hub moving in and out from lack of needle bearings....Geeves bro you pasted a link in the past so could this be a likely cause? http://clubisuzu.com/viewtopic.php?f=25&t=3420
I've considered engine and gearbox mounts and exhaust brackets but the hi shimmer sound at speed I think really leads me to asking why are my tyres doing this.
I can't hear any graunching sounds from those areas while driving and my tyres are each at 34psi.
My wheels have rotated around from front to rear incl with the new spare and weren't picked up for out of roundness at the first wheel balance and alignment.
Couldn't get them wheel balanced today - saturday 1/2 days.

Re: 90km/hr Vibration - CV Inner/Outer
Up front the only rotating components are the tyres rims hub assembly and brake disc. You appear to have eliminated tyres with the front rear swap. Have you had the discs machined? Is there a possibility of a bent wheel stud or wheel mounting flange. You will need a dial guage to test these.
Otherwise your looking at front suspension components although Im not convinced. Shock absorbers worn can cause strange things and your model is the one that had an issue of a crack in the chassis that showed as a strange noise
