tyre damage ??

[John B]

Hi all I've noticed over the last few weeks that when I'm turning on full lock right hand down I'm getting a bit of tyre drag from the front near side and have noticed that I've got chunks out of the tyre all the way around on the outside edge, and also noticed that if I jack the front of the car up the wheel with the damaged tyre is harder to turn by hand than the other. Going back a few months ago I changed all the oils in the diffs and used 80/90 GL5 in the front diff ???? What you think campers could it even be linked to the vibration I get at 60 mph ??

Have you tried changing the wheels from front to back.
Have the wheels re balanced.
If it's ripping chunks out make sure that they are not catching on any thing.
Check wheel bearings are free and adjusted properly.
Check brakes for binding. The slider pins have a habit of seizing up.
Condition of auto hub.
Have tracking checked again.
No tyre place can do it properly round here so I go to a commercial tyre fitter.
Just a few things off the top of my head.

One front is more difficult to spin due to position of diff :thumb2

Chinks are legal as long as no cord or cracking is visible, still, what is happening? :nenau

That's true on later models with flanged hubs.
On a t reg it should have auto hubs so resistance on front wheels should be the same.

But still diff is to one side no? So one shaft is longer? :nenau

It's a 2004 with fixed hubs sorry its my own plate. It's not a brake problem and tracking is fine.

 

[elty001]

Could be a front diff problem.
But tyre wear is normally tracking or camber/castor problem.
Are the tyres standard size,been replaced recently.

Check the age of the tyre too, there is an oval shape stamped on the tyre wall, it should have 4 numbers in it. These denote the month and year the tyre was made.
Maybe the tyre is an old stock :nenau

 

[John B]

Should I put lsd oil in front diff like I did with the back ??

 

[firebobby]

No :thumb2

 

[rustic]

No :thumb2

I agree...
Definitely NO!
The front diff is a standard diff, LSD oil will do it no good at all.

TIP:-
LSDs have special friction plates in, and the LSD oil is essential for these, if non LSD oil is used in an LSD, it can damage it, and if put in, in error, then two complete changes with proper LSD oil is required ASAP, a few hundred miles apart, to flush it out.:thumb2

I like to keep the tyres on my rear axle as a matched pair, ie same type, same tread depth, saves the LSD from working too hard under normal road use.:thumb2

Noooo, it is not an oil problem, if chunks are taken from your tyre it is hitting something that it should not be, the fact that it is harder to turn than the other suggest severe alignment problems although this could also be a brake problem, but chunks from the tyre is not acceptable, I think you should take it to an independent tyre Co for a good check, not the likes of quickfit, I think you have a very serious problem and would be very careful driving it, Rick

No one has mentioned UJ's on front prop shaft, this can also be the cause of vibration problems at high speed, quite a few issues with this.

Fixed hubs, and Nissan's penny pinching removal of the three grease nipples on the front two UJ's and the slider joint, leads to increased wear on these parts.:doh

The older auto hub versions, had the grease nipples, but the shafts only turned in 4 wheel drive, so got no use really, more likely to seize up with no use lol...:lol

Just for the record...
No one has asked the big question...:nenau
You are not using the vehicle in 4wheel drive on tarmac roads are you...:augie:augie ?
Now THIS WILL shred tyres, and damage the transmission too...
Sorry had to ask....:nenau

True actually, chunks missing are not good, unless it is self inflicted ( bad parking)

Believe it or not I see chunks missing out of sidewall all the time on these posh jags :lol

 

[firebobby]

OR an old tyre as I have already stated, I had this happen to a tyre on a works van, the tread came off in chunks.

But still diff is to one side no? So one shaft is longer? :nenau

Other than initial inertia of the additional mass in the longer shaft, what effect would you think this would have?:nenau

The parts in the front diff for the left and right shaft will be the same, so friction within the front diff should be the same for both sides.

So the non central position of the front diff will have no noticeable effect on the effort to turn either front wheel when turning by hand.

Unless there is a mechanical fault with the front diff.

Are you sure rustic? I'm sure ageees ago when I first got my baby, I happened to spin the front wheels and noticed that one was harder to turn than the other.

Brakes are all good on mine too.

Well mine are auto hubs, so have no experience of trying one with fixed hubs, but using engineering logic, I can't really see a reason for them to be different...:nenau


If anyone can explain otherwise...
