Rubbing sound when making a left hand turn...

skullman80 · 07-02-2011, 08:04 AM

Ok... so I just got my first Jeep, a 2004 Grand Cherokee Limited Edition with about 79k on it.

... with that being said yesterday after I started driving it for a bit, I noticed a slight vibration/humming sound when making a left hand turn. This only happens when making a left hand turn, and it seems like it's more pronounced the sharper it is.

I don't think the tires are rubbing, any ideas?

The other thing that pops up as soon as I turn my jeep on is bad tire sensor/sensor missing on the EVIC. Now when I test drove this thing, I didn't drive a full 10 miles, so I think that's why this didn't pop up then.

I read through the book, and how to retrain the sensors as I thought that might be the the problem, but no matter what I do I cannot get the horn to chirp as the book says when you put that little round magnet on the stem of the tire. It just stays at testing left front tire/wheel and eventually aborts because I've taken to much time.

I'm hoping this is an easy fix, I got this at a dealer and did get an extended warranty on it, but they can't get me in till mid next week, so I was hoping for some things I might be able to check/try myself.

Thanks!

I do not know much about WJs, but I had an issue with my TJ where I heard a noise from under the Jeep only when turning right (and braking hard). It turned out to be my front driveshaft rubbing against the exhaust down pipe. I'm not saying this is definitely your issue, but check to make sure your driveshaft is not rubbing something.

The rubbing sound could be low friction modifier In the diffs.

So changing the differentials might do the trick?

Is this easy to do?

This stuff is kind of greek to me, but I'm trying to learn.

Add FM to your diff fluid If you have the Quadradrive??? Or change diff fluid and transfer case fluid. If its a Quadradrive its very important you put the right Stuff in There. Nv-247 fluid only for transfer case. 75w-140 syntetic gear oil front and rear diff. Add about 4oz FM (friction modifier) to both diffs.

If you dont have the Quadradrive, dont care of What i wrote.

Post What 4x4 system you have so We can give you right recomandations about fluids etc.

I do have a Quadradrive yes.

Is that what you mean by 4X4 system?

Yes, change all fluids and use the proper ones as described in pre post. That Will fix your problem.

Am I doing any damage waiting til mid next week to do this? That's my only concern.

I don't know if I feel I can do it, and that's the earliest the dealer can get me in to have it looked at.

Do you think this problem would have thrown a bad tire sensor problem as well on the EVIC?

The fluid change Are quit easy If you have some minor tools and a place to do it and a little skills. No lift needed.

I Had bindings in My diff for a while without braking anything but i recomend you fix it, the faster the better.

Well hopefully that is all that it is, I'll find out soon enough. Thanks for the suggestion.

Hopefully the sensor isn't bad on one of the tires either, but I'll have that looked at by the dealer too. I tried to retrain them, but had no luck.

My FM and fluid was low on my front and the axle would feel locked when I turned corners. This was do to a bad inner axle shaft seal.
