Tyres screeching

[rickydicky]

Grateful for some advice/help.

When I bought my Terrano a few months ago it had (and still does) Runway Enduro A/T tyres on it.

Even if I go slowly around a corner the tyres screech and I get the looks from others drivers thinking why the hell is he going so fast ! It also can be a bit hairy in the wet.

So, I checked some of the forums and one of the possibilities was the rear diff oil. So I changed that to the recommended fluid and still no difference.

So as I don't go off road much ( b4 you ask, Why buy an off-roader ? It's because you can carry loads of stuff, without much loss on performance), and I'm thinking maybe it's the deep tread on the tyres and hence not as much rubber on the road surface, hence the screeching.

So grateful for ideas on the above and suggestions on a more road suitable tyre.

many thanks

Have you had your tracking checked? These trucks are notoriously bad to track up.

Can you tell if the noise is from the front or rear.

 

[rickydicky]

Thanks for the quick response.

No, I havn't had the tracking checked.

It's difficult to tell, but I think it's coming from the back. Also, it feels like the back is trying to slip out at the back in the wet when turning.

Runway Enduro, are really good tyres for the money they have very good reviews too, although occasionally i get a small screech on full lock in a car park or alike
they grip really well in the wet too... believe me i push it to the limit

got to ask....... are sure its not the power steering belt ? stupid i know but at least it eliminates that

and it wont be the tyres

you are in 2wd when this happens i hope ?

 

[extreme-4x4]

also check tyre presure i run on 30psi front and back.... but that will cause loads of of topic posts


see sticker inside drivers door for correct psi

 

[rickydicky]

I havn't checked the steering belt. Would it screech on full lock when not moving ?

I was only convinced it was the tyres because of the lack of grip in the wet. I'm not going fast at all when the tyres screech.

Yep, it's in 2 wheel drive.

I'll check the tyre pressures.

 

[extreme-4x4]

how does the truck drive through all speeds.... any woble or shaking even very slight can give clues to whats happening

the first one id say is check your preasures and its free , depending where you go.
while your there run your hands around the tyres all over and have a good feel for lumps, high spots and tread depth... is it even do they look right

I'm getting tyre screaching from the front tyres mainly on right hand bends & round abouts, but this has only happened since raising the front end back up to where it should be :? If it's kicking the back end out I would change the rear diff oil (LSD oil only)

 

[rickydicky]

I've changed the oil to an LSD as noted from previous posts.

Drives absolutely fine, no shake or wobble at lwo or high speeds.

I'll get out over the next couple of days and check the tyres and pressures.

I've just learned to live with it over the last few months, convinced it was the tread. But I think now the tread is probably not the issue.

I'll report back.

People hae found that changing the poil, running it for 2-500 miles and ten changing it again works wonders. The first chage needs to time to clean te friction plates up and then you chage it to get rid of the dirty oil.

I havn't checked the steering belt. Would it screech on full lock when not moving ?

Yes a power steering belt could scream when not moving if held tight against the lock stop.


As stated check tyre pressures, but it could just be your LSD is pretty tight, my old one used to slip the tyres when turning tightly in ca parks but being on mud tyres it didn't really screech but you could hear and feel it happening. A second change of oil would certainly be worth a go, tends to cure the tail happy attitude.

Is there a guide on how to do this? as i have never done it?

 

[rickydicky]

I'll check the tyre pressures and general condition first and then change the diff oil.

See what happens then.

I assume you mean changing the diff oil.

As yours is a 05 model you should be just about at your first scheduled change 3yrs/36000miles. Don't think theres a download anywhere, its fairly straightforward.

You need 2.8L of an API GL5LS compliant gear oil.You'll need a 1/2" drive ratchet or similar square drive to remove the plugs

Remove filled plug (on back of axle) first to make sure you can get it out,

then remove drain plug and drop oil into suitable container.

Refit drain plug, fill with oil till it just dribbles out of filler hole, replace filler plug.

Great thanks for that.
It has done a few more miles than that. up on 54k

If you were having it dealer serviced at 36K it should have been done - though there is no gaurentee they put the correct oil in of course.

Don't think that when dealers change the oil they put the right stuff in, they don't often sell LSD oil from their spares department. I tried 3 dealers, they said we just put ordinary stuff in..... from that big drum over there....

I had similar problems and used Comma LSD oil 80W90 GL5.
MUST be LSD oil.
As per the other threads, you may need a second change to clear out the wrong oil. When you change the oil, it looks like graphite... silvery grey.. contaminated with the friction material. (this is normal after a few thousand miles).
Also run both rear tyres with the same tread depth and type, same pressures etc and you will notice the difference.
Otherwise the LSD will work over time.
My tyres screech on dry multi-story car parks at very low speed on near full lock. So some screech is normal.
You will need just under 3 litres of LSD oil, a 1/2" wrench, the 1/2" drive fits the plugs as they are. Undo the filler first, half way up the rear diff ( in-case you can't get it out later,) and drain the bottom. You can do this job while it's sat on the drive. No jack required. 20 minute job......Max and that includes 2 cups of tea waiting for the oil to drain. :lol: :lol:
Hope this helps.
best regards, Rustic

I hear a lot about the use of Molyslip, can this be used in a rear diff or is it a definite no,no. ?

Hi some time ago I contacted Richard at Molyslip (link on this site)
He suggested the following product:

"If you plan to do the rear diff, she has an LSD back end so you want to use Multiglide 110ml."

Not used it myself in the rear diff, but I used a combination of Molyslip and Multiglide in the gearbox which reduced the whine in the box by over 80%.
I also use the molyslip engine version, it reduces the stress on the starter motor as it turns over faster and is very easy to start.
Hope this helps. if you want to know info on how much for engine/ gearbox I'll post the info again.
Best regards Rustic

Well, I did the first part of the checks at the weekend.

Although the tyres "looked" OK, I checked the pressures anyway and sure enough they were all over the place. Set them to the right pressures back and front and lo and behold it makes a hell of a difference to the handling.

Can't believe they are so sensitive to varying pressures (they weren't that much out !).

Anyway, going to change the oil in the rear diff this weekend (it was too cold last weekend !).

thanks for all your suggestions.

 

[extreme-4x4]

Tyre pressure is as important as checking your oil or water... if not more so............ tyre pressure can kill you. costs loads in fuel and effects braking

and causes extra wear on stearing and suspension to name just a few


always check your presure at least once a week
