Revised steering noise TSB: JTB00034v3

 

ha....none....so i did tire smoking reverse sliding doughnuts!!!!!

 

Guess what, I bought the additive and followed the directions in the service allert and the squeak is gone for now. I will keep my fingers crossed. Don R

 

I picked up the additive this morning and followed the procedure as the TSB specifies immediately after getting home from Greensboro while the power steering fluid was still hot from the highway. While the "coo" did not completely disappear immediately, it did quiet down considerably and dropped to a lower pitch. We'll see if additional driving this week continues to make progress towards silencing the noise once and for all....

 

Update:

Two days have passed since I poured the additive into our power steering fluid reservoir and the steering wheel is now as silent as a tomb. Not sure what's in the additive (no ingredients were printed on the bottle), but it certainly did the job with our car....

 

its been about a week for me and its 90% gone

 

Well, the addative and procedures in the TSB got rid of the squeak but it came back the next day.It was less loud. I arived at a meeting early so I went through the procedures in the TSB again and the squeak went away again. We will see if it stays away.

 

One thing I did before having the dealer add the additive was to vacuum out the P/S reservoir several times and refill it with synthetic P/S fluid. I use a turkey baster and it makes it very easy. I did not know about the additive at that time. The fluid I removed was very black and junky looking. The plastic strainer in top of the P/S reservoir can be removed by depressing the two tabs that are visible if you look down inside the fill cap. I use two small screw drivers to push in and then pry up.

I think a fluid change would be a plus. It seems the noise is related to deposits in the rack itself. I have ordered another bottle of magic elixir myself in case the noise returns in the future!!!

I also removed sufficient fluid from the reservoir before pouring the additive in. I went with a previously-used plastic disposable veterinary hypodermic needle that I keep a stash of for situations just like this one. Our car's fluid was still a very clean red color so I didn't consider changing it....

Our car's owners manual says that the factory-supplied power steering fluid is "Dextron III". I assume that is simply a spelling misprint for Dexron III, which has been around for many years and is primarily used as an automatic transmission fluid here in the U.S. Can anyone out there confirm that the S-Type's factory-filled power steering fluid is indeed Dexron III?

 

Well, the squeak is back. When the fluid is cool, quiet. Then it starts again when hot. I think I will try sucking out as much of the Dextron III (Dexron?) as posible, replace that stuff, add new addative and see what happens. I can't stand that squeak!!!!!!!!!!!1

 

I believe the recommendation is synth Dex III

 

Don,

Good idea to try it again with clean Dexron III in the reservoir. Before you pour the additive in, make certain that you've driven for 10 miles or so to bring the temperatures up underneath the hood. Also, when you drain the reservoir and pour in the new fluid, fill it to just the minimum mark, perhaps even a little less. Let the additive be the fluid that takes it up to the normal mark. Then work your steering wheel lock-to-lock for the 20 or 30 times described in the TSB. Hopefully that will do it for you this time....

Forgot to mention - the Jaguar dealership confirmed that our owners manuals spell it wrong. It is indeed Dexron III. Maybe they call it "Dextron" in the UK....

 

ALL, guess what (knock on wood) I never got around to replacing the fluid but that squeak is gone after about a week of driving after adding the magic juice. We'll see. DonR

 

This was a very minor issue for awhile, but recently has become noticably louder. Still not a huge annoyance but enough that I think I'll address it, especially after reading this thread.

Just to make sure I understand correctly, to remove the PS fluid I have to suck it out from where I pour it in, there is no drain correct?

 

Correct. Some use an old turkey baster. I use an old veterinary plastic hypodermic needle....

 

I have the same squeak looks like monday go to Marin Jag and get a bottle of the secret sauce. I'll also do a fluid change while I'm at it.

 

I'm not certain that all of these noise issues are the same thing. Certainly the TSB posted above isn't additive oriented. In my case the noise sounds like it's inside the car, perhaps more like what's described in the TSB in this thread. But my vin number is not in the list applicable range?

I also have the judder effect at low speeds when turning the wheel. It's not something you expect from a relatively high end luxury vehicle.

What's interesting is that neither the local dealership or another person from Jaguar corporate knows anything about this additive. That's weird.

 

I had the noise, did some hunting, used the additive and all was good. So, all I really have are brief notes from way back:
ST211-04 (Issue 6) rear PAS seal (& can use some ATF) 12pp
& S211-04v6 14pp (but apparently the same)
JTB00034v3 adjust steering column re bushing 6pp VIN N38511-N80136
JTB00055 friction modifier additive 4pp M45255-on
friction modifier C2S48887

There was a TSB about a hose for the PAS which mine already had replaced so I'm not sure if that's in the above.

Some/most will be on this forum in the FAQs / TSBs or the www.jaguarforum.co.uk, otherwise jag's TOPIx.

I've seen a few people mention that the additive wasn't the fix but a bushing on the steering wheel column was. In all cases I understand the noise appears to be in the cabin even when it's not.

Oh, also

I'm trying a new dealership for my next service.

I'm going to use the phrase "just fix it OK?" and be insistent.
