vr steering trick

[markhayes]

Can ane 1 help , just had bearings done, in front ,an bushs are new new power steering pump , Problem is when i turn right at slow speeds applying acceleration my left wheel starts to sound likewhen a bearing has gone ,crunchin an a bit of a streching noise or a strain ,it some times is really bad then some times it cant be heard ,i might have a buckled brake disc but im thinkin that cant make a sound such as that. an as i steer tighter in to the corner it gradually get louder an i feel that as i start to straighten up its lingering on longer each day i thought it was bearings thats why i chandged em but it didnt seem to work.vr holden 94 v6

Mate if you are not very mechanically minded,then go and get a mechanic to look at it.It doesn't sound safe at all and something is obviously very wrong if its making a crunching noise.If you do decide to go to a mechanic, and are going to drive it there,do it very slowly.It could be any number of things causing it.

thanks but pre advice is what im looking for so i dont get caught in the same trap of get something fixed an take home something else broken around here you pay to get things fixed twice instead of once thanks ane way

All you can do is go over everything and check it all,jack it up,spin the wheels(listen to the bearings) and try pulling and pushing them.(check for sideways movement etc)Check the bushes for wear,if they look squashed and cracked and generally worn then they most likely need replacing.The swaybar link bushes are known for wearing out quickly,give em a good look over.The struts wear out with age,if they are the originals,then they might be due for replacement.And check the steering rack,jack up the front wheels and turn the wheels left and right full lock.Do this by turning the front wheels and feel and listen for any roughness in the rack as it turns from lock to lock.

cool thanks brett ill do that ,i was also told it could be ball joints, does that sound likly to you,

[westbad]

could quite possibly be ball joints, or could also be the strut top bearing, like brett said you will have to jack the car up and have a real good look around.

I had a similar sound in my VS - it happened when on hard left turns usually noticed in a carpark when doing rapid wheel movements to go into a parking slot and always on full lock. In my case it turned out to be the inner edge of the tyre rim making contact with the tierod end...apparently the wheels, despite being factory issue, are just a bit wider than the standard steel rims and (only) just scrape causing a very loud noise inside the cabin. Mine only just made contact and left a hardly detectable scrape mark on the inside rim. The sound is like scraping a shovel or spade blade across concrete.

[markhayes]

it does sound like a spade scraping concrete but i havent found any tire rubbing any where even a small amount i should have seen its pretty tidy in the wheel arch for that model ,an i only hear the noise during turning from stop or slow cornering during speed increase ,an lingres for about 5 sec while i start to straighten so i thinking ball joints would be the go ,it feels sometimes like i need a real bad wheel allignment an the car engine tends to struggle a little when the noise is there an im increasing speed not a major struggle a tiny spatter ,But when i put full lock on either direction whilst in park the revs drop for a second an then pick up at normal idol speed,can that relate to a ball joint.?

[hako]

There is another possibility - check the brake disc on the side the noise comes from - look at the outer edge of the disc where the pad rubs...the shiny smooth surface - on the outer edge where the shiny bit meets the rough unrubbed/unmachined disc surface - this rough bit can contact the brake pad and make that rough noise on hard slow turns. Inspect this edge carefully and see if you can detect where the pad is contacting the rough bit. I used an angle grinder to remove the rough edge and this worked on mine.
If you don't quite understand what I'm getting at with the above rough (very!) explanation I can take a pix in the morning.

What Hako said just reminded me of a mate ,he had a brake pad spring snap off,and it made the pad scrape on the disk,making a bad noise,but his was a constant noise,it could be worth a look though.

Mine had the same problem. New bushes helped.

[markhayes]

i have new bushs already didnt help i checked brake disc no signs when i pulled it ,off i still sanded the outer edges and no diffrence, thanks for all the help from everyone who had some good ideas . I have also noticed over the last few days its getting worse now i am starting to get vibration an it now only happens when im increasing speed, when im rolling its not their , when i reach 50 or higher rolling no noise but when accelrating its pretty shaky,.An as the engine revs it whilst travelling the noise shakes harder untilli release the accelaration,

[Brett_jjj]

Id be checking the driveshaft and uni joints also check the engine and gearbox/trans mounts.

[hako]

If it is felt thru the steering wheel try swapping front wheels for rear ones - I had a noise one time that was caused by cheap tyres delaminating.

[markhayes]

sounds good ill have a look thanks brett

[markhayes]

the sound pretty much comes from directly the left front side an as i have loud tyres i can distigush that its not them to much negative effects to the vehicle handling.

[Brett_jjj]

You would think that if it was one of the tyres or wheels,it would be a constant noise/vibration.

[hako]

When I had this tyre vibration it was most pronounced on left turns at slow speeds...gradually got louder and I figured it was wheel bearing - replaced RH bearing (as it takes load on LH turns) but to no avail...then discs, pads and LH bearing. No improvement and just got louder and began to feel feedback thru the steering wheel on corners. Then I ran my hands over the surface of the front tyres and felt a slight undulation or ridging on the tread....swapped front for rear and fixed it ....after spending over $500 on parts!.
I also did a search on tyres and found that this brand was currently being recalled in the USA as they did not have a 'tread breaker' or something like that which prevents the tyre cords from flexing unler load. It was this flexing undert side load that caused the tread problems which then caused the vibrations.
So, it costs nothing but may be the problem.

[markhayes]

that sounds troublesome, but the chance that you bought tyres that were ordered from a major corporation from overseas that were faulty are pretty slim ,An i would think the same for myself but every bit of info help ill get back to you with a anwser, thanks

[markhayes]

had it all checked everything in the clear except engine mounts an suspension support strut now i thought both sides would make a noise but it only does it on the left but my mechanic said if i fix the support strut an engine mounts the noise would go ?now i also spoke to someone else who told me to change my steering rack ,which should i do or is both in order ? any 1

[hako]

Do the cheapest first - the engine mount.
Re the tyres which I had and were recalled in the USA, they were widely sold in Australia (Wanli brand) and despite many returns under warranty, no recall was made but that's not surprising as the Yanks are much more consumer orientated.
Did you swap them to check?
Here is another thread on those tyres: opinions on WANLI tyres plz... gettin bad vibrations!!

[markhayes]

just reading the wanli profile ,alot of trouble those tyres sound like i have not changed em yet but i think i will just to see , ill let u know an on the same case ill put out the word on wanli an let evryone know what brand of tyre i have iff this solves my problem.
