Distinct moaning from the rear when I make a turn or sharp curve @ speed, seems more pronounced if I give it gas in the curve/turn.

Not a real abrasive sound it's really a moaning sound, I will try & video it tonight. Any usual suspects back there to address ?!

Tires are new & rear diff. oil was changed 700 miles ago

The game is afoot lol.

 

Well that was a swift turn of events trying to record the noises lol ! I'd just filled my car up from a different than norm station(same brand & grade of fuel). I'd let the fuel get way lower than normal I usually fill up @ quarter of a tank & it was near the red mark on the gauge this time.

First start from filling I got a rough idle that cleared only to render "Restricted Performance". I pulled over cleared errors w/ the torque app & it's been smooth sailing since. I gather my low fuel situation stirred up some debris from the bottom of the tank couple that w/ suspect fuel from a new fuel source. Here's the codes I pulled after the "RP" event P0300,P1316,P1111. Thinking it may be time to do plugs/coils ?!

Well I did capture the moaning noise on turns during all that. The steering wheel is also making a reeling/whining noise that's new, so I suspect they are all steering related. I will check the power steering fluid a bit later tonight.

1st video is the noise on turning & curves. The moan/drone @ about 2 seconds to 5. Of course I had to battle a sneeze/sniffle right when it begins lol.

2nd video's the steering wheel's reeling noise w/ me sitting still moving the wheel.

Any clues from the wise & venerable clan here ?!

Update :

Just checked power steering fluid it was low & very muddy/cruddy looking. I turkey baster'ed out as I could & added new Lucas. The sitting still steering squeal from vid #2 appears gone. But alas as I solve one problem , another surfaces lol. I close the hood & the driver's side refuses to catch, I inspect to find what appears to be a shattered receptacle/catch cup ?



Let's hope on the next drive that the groan/moan on turn's a forgotten memory. But either way that PS fluid was so heavy w/ debris it looked as if it had graphite suspended in it, so it will be flushed & replaced. My serpentine belt tensioner & pulley have also been acting up prior to this & due to be replaced soon, so maybe it's all relative. Was semi-dreading whilst reading all the wheel bearing etc. threads w/ similar symptoms, so hoping mine's all power steering affiliated.

 

It is a bitch when these things get old.

I can feel your pain from here. Lucas makes a power steering oil enhancer that does a nice job of lubing the seals. Quieted my Jag's and on the Range Rover.

WD 40 or Amzoil's equivalent will quiet the clock spring.

Try greasing the zerk fittings on each side of the differential to quiet the noise from the rear on turns; maybe renew the diff oil; bearings?

 

KC, have you checked your propshaft bearing strap? Your bearing may be ok, but it may be the rubber grommet that holds it in place. Check how mine was torn when I did my bearing. https://www.jaguarforums.com/forum/x...g-info-188400/ ...didn't you just do your flex disc's? If not, check them also...again in that link for what mine looked like.

Have you checked this TSB for the steering... https://www.dropbox.com/s/njtwx7lm09...tling.pdf?dl=0

 

The power steering fluid refresh has solved my turning noises for now lol.

 

The steering spring noise has returned, mine is just like this member's scenario linked below, so I will follow suite.

Edit :

Any threads on opening up the air bags to lube it's holding springs, thanks.

 

If I remember right, there's two bolts that hold it in place, look on the back of the wheel as you point it at 3 and 9 oclock to expose each one. Disconnect the battery and let it sit a few minutes first!

 

I know there's a TSB on this because I've read it. It may not be on site, but possibly on the Jagrepair.com site.

 

Lots of threads on removing the steering wheel: try searching with keywords (maybe on Google too, seems to work better for finding stuff on this forum): steering wheel removal X308, multifunction switch (where my writeup is, I think); X308 airbag . . . .

 

I tried searching for Airbag removal and Divorce came up....

 

Sound about right lol.

 

Been there . . . four times, but who'se counting?

 

Dang....I learned after the 1st time

 

Alimony x 2 is no fun either, my wallet needed an airbag mechanism to keep attorneys from crashing into it lol. "but who'se counting?" the answer is, lawyers lol !

But back on the subject @ hand I read my noise is likely the springs(not clock spring) that hold the air bag are dry & making noise when the steering wheel turns. But from the great pics below I don't see what to lube ?!

Have you tried moving it as you disassembled it to determine the cause? I had a piece of paper (unknownly) fall into my column behind the wheel on my Corvette. It drove me nuts and job I did not want to do. After I pulled the wheel off, it fell out, I checked the rotation and the noise was gone. It was one of those, grrrrrr moments, but a simple resolution. Otherwise I may had torn down the column completely since I had just installed new signal/cruise switches.

 

Well the moaning is back & it's always brought about after I drive a certain road, haunted lol ?!

Turning @ a very slow speed no noise, any speed it's howling.

Here is another video.

Fluid's topped off, so not sure what it is as of yet.

 

The 4 pozi screws, remove them and you can access the springs, they're sat under the horn push alloy bars.

 

Thanks, now onto the howling rear end on turns, I'm going to go with rear wheel bearings.

See the kits on E-Bay but about how long of a job is this .

 

Recommend not going cheap on the bearing and get the real brand deal and torque properly

 

Looking @ these.
