Lower steering column

Postby XJ4081 » Fri Aug 16, 2019 11:44 pm

Hello,

I think I finally found the reason for the play in my steering, it's the lower steering column. To be exactly, the clearance where the lower joint is put into the steering column itself. The play directly corresponds to the amount the steering wheel can be turned without the wheels moving. Unfortunately I cannot find a spare part anywhere. Is there a way to refurbish this part (HMD9501AA)?

I had the exact same issue on my early 93MY Sovereign 4.0. As always there’s lots of different part numbers, for no obvious reason.
I may have a spare? PM me if you are interested.

To VIN 673844 it’s the same p/n for LHD/ RHD. But after that VIN, a different part number for LHD/ RHD.

At least it’s not V12 specific. Gives you more options.

I guess your part is RHD? As you already stated from VIN 673... LHD und RHD are different part numbers :( .

I have already called/mailed various part dealers but none has that part available. There is a used one offered in the Netherlands, maybe that could be an option. But I am a bit insecure whether a used part would be really a good choice since mine has just done 100K km and is already worn out.

I am wondering if it could be refurbished somehow? The brute force method could be to simply weld a small bit of metal onto that gap :? .

A- I don’t know a way to refurbish.

B- with limited options available, I would suggest it’s worth “a punt” at a used part.

C- I don’t believe this fault is very common. I have only heard it discussed twice on here. Mine and yours.
So your odds at success are high.

I've heard about another case in a german Jaguar forum (but could also have been a X300/308) and one of the part dealers I talked to told me that he had several requests for that part in the past (that's actually why he has none left). So it's surely not as common as a leaking steering pump or a worn out steering rack, but it seems to happen occasionally. It probably depends on how the previous owners treated it in the past. If they maybe had a narrow driveway/garage, requiring heavy steering when the car stood still, it is more likely to happen.

But it seems that there is no other way than to go for a used part and hope it does better than mine.

I finally managed to get a used LHD part, it looks good at first sight, but I wonder if there is a way to check whether is still functional before getting it into the car (I also found out what that cylindric shaped section is good for - it is the steering damper, that used to be a separate part on earlier models and I guess it is also responsible for the play that I am facing).

And the second question is how I could get it into the car? Accessing the lower bolt where it is attached to the steering rack is no problem, even on the V12, but the upper part, which is attached to the universal joint is not accessible from below the car, it's behind that grommet that leads it inside the body. Would it be necessary to remove the steering wheel (and maybe even the whole dashboard) to access it from inside the car? Or can that grommet be fiddled out and than the upper bolt is easily accessible even being inside the body (which I think is almost impossible with the engine being in place ... at least the left exhaust pipe + manifold has to be removed)?

Oliver

Edit: Or does the drawing from the parts catalog really tell me that the lower steering column is simply plugged into the universal joint but not additionally fixated by any bolt?

I guess I will chime in here.

The part you are referring to is indeed the steering damper. There has to be some play in it, otherwise I won't "damp". Therefore, upper and lower parts are connected by some vulcanized rubber inside. The play however is limited by two excentric metal stops - visible from the lower end. I suspected this to be responsible for some of the inaccuracy of the steering, too. I went ahead and welded the two pieces together at the excentric stops to eliminate any play. I hasn't changed the steering experience noticeably. Except for some placebo effect maybe.

The good news is: The upper end ends in the left footwell at the steering U-joint (it has 2 bolts). It's rather easy to disassemble - the real pig is the lower joint (on the V12).

I have achieved the greatest effect on steering play by doing this: https://www.jaguarforums.com/forum/xj40-xj81-25/steering-rack-stiffening-bushes-diy-134396/
I had two pieces made from 3mm tivar (or similar). I didn't bother with the circumferential groove though. I put cable ties instead.

Best
Guido

Good info, thanks for sharing.
I suppose this issue will become much more common as the years roll on.
