What is the telltale your rear bearings are shot I jacked up the rear end spun the wheels and could hear grating.

And when 4wding on sat I could a clunking when steering hard left or right but only in 4wd.

help!!!

Grating noise sounds like wheel bearings.

clunking while turning sounds like CVs mate

I thought it may be bad news, thanks any way

[89_tintop]

Thats what it sounds like any way.....

Look on the upside if it is that, you could add some lockers and chromo axels and all the goodies while it is apart.

if its only 1 clunk when turning, maybe 2 then might be wheel bearings. if its a CV it'll click with each rotation and is usually pretty loud. A bearing clunk feels like you've left a u-bolt a bit loose. Either way, jack the wheel up and check for movement by holding the top and bottom of the tyre and pushing/pulling towards and away from the car, if it moves your bearings are stuffed.

I tried the wheel movement test and it is tight although i remember hear roaring sound on the freeway(like the sound of muddies) so i think they on the way out

[alien]

have you checked the diff center?

[whatulookinat]

No i havent i had the diff pinion seal done last week mechanic didny say anything not that he may have noticed How do check diff apart from filings on sump plugs.

eventually a failing rear wheel bearing will leak oil out of the rear brake drum, wheel bearing hum or grind will often get louder and higher pitched with traveling speed,

Diff noises will get louder with traveling speed but will change pitch or sound level if your cruising, coasting or accelerating

these signs are very general, trying to hear noises like these with roof flapping etc can be difficult, probably not the best advise but I used to just turn the radio up till things got worse, eg oil leak, pinion play smoke etc than fix it. it makes for an interesting story to tell. and is a good learning curve.

It is possible that the bearing can collapse before you see an oil leak. Infact the only reasons you WOULD see an oil leak from a bearing related issue, would be from excess heat caused by a failing bearing, or the seal being damged when the bearing starts to collapse, causing the axle to drop and tear the seal. At this point it woud become a job for the towtruck

Everything I post up here is to try help others with there questions. its from my experience over the past 15 yrs of owning and driving Suzukis. Not everything in my experience will you find in a text book nor will many ppl agree with. But its not bullshit!! Its happened many times to me, otherwise I would not be sharing my ideas with others. I've needed a towtruck once in that 15yrs after a rear diff colapsing. I used to do a rear wheel bearing every 2 months when I drove live an idiot in the bush trying to drive thru every bit of mud I could find. I used a guide to myself with wheel bearings, once I could hear the grumble, I had about 4 weeks or say 1000km's to fix it. once the oil was leaking it was time to fix it. never failed me this guide. its not recommended but its reality. I've driven from bowral to St peters with a leaking wheel bearing on the hume with smoke pissing out by the time I was at cambelltown, but by taking it easy I got home and fixed it!

anything is possible. I'm not trying to show ppl that i think I know everything Just simply sharing my experiences to help others. Its getting a bit annoying ppl trying to prove my reality wrong. its to late, its already happened.

I follow the book of hard knocks as well as the text book.
just because I don't have a high post count doesn't mean I'm an idiot.

Calm down champ. Nobody is having a go at you Like you I was simply sharing my experience with wheel bearings on sierras. Shit I drove my ute for 3 months with adead bearing just to see how long it would last.

And you have no post count. Same as everyone else

my rant is over than

I have had a roaring noise on a car i owned once, it eventually went Bang... turned out it was a Uni Joint, and it eventually let go... dont know if its the same roaring noise, but might pay to check your Uni Joints... and when i had my 89 Vit, my front wheel bearings were very worn, and i found there was movement when i grabbed the tyre and wiggled it, not much, but there was movement...

thanks for info guys
