STEERING RACK PLAY

Postby XJ40-MARK » Fri Oct 10, 2014 6:23 pm

this related to my mot thread, but given someone might have the same issue at some point, i thought i`d start a new thread, to make it easier to search for.
i took my car for mot in september and although it passed, we did spot that whilst the steering was being rocked from side to side, the steering rack was moving from side to side, roughly about 10-15mm of total movement, which of course they should`nt do. this is something your most likely only going to spot or find out about, at mot time. i certainly was`nt aware of it and i had`nt felt any difference in the steering, HOWEVER, with hindsight now, it has occured to me that perhaps the steering has`nt seemed as sharp as it was when i first got the car, but if this rack movement has crept up on me, then i guess i would`nt!
the cause of the issue is the brackets, that hold the rack in place. at the factory, the rack itself is bonded to the brackets, which is then bolted to the subframe, however, over the years, this bonding goes and the rack breaks free of the brackets, hence the sideways movement of the rack on steering. now short term, i don`t think this is a major panic about issue, but clearly, the rack is`nt meant to move. my issue is the pipes that go to the rack, whilst there maybe slight flex in these pipes, constant movement in them from side to side, can`t be good in the long run.
now the expensive option i guess, is to replace the rack, or get them re-bonded to the brackets, both of which involve removing the rack. now i`m not sure about you guys, but i don`t particularly fancy removing a perfectly good, leak free rack, so here`s the solution.
this must clearly be an issue on these cars, because you can buy a kit for these racks, which stops the sideways movement and it looks like this;

Image

you get 2 nylon rings/bushes and wire ties, which literally just slide over the rack, next to the brackets. now according to the ad off ebay from where i brought these (BLACK COUNTRY JAGUAR), these take minutes to fit (now where have i heard that one before). now its not minutes, but its not hours either, as they are fiddly, because of the obstruction of the brackets, plus, you need to get the steering set just right, to open the gap that you need to slot these into, so not minutes, but allow half hour to an hour in total!
now by drawing illustration, this is where the bush goes;

Image

and from underneath the car and looking at the rack, this is the gap that you`ll see;

Image

the bushes are easy to push in place, if a little fiddly because of the brackets, but to make it easier, soak the area with WD40 beforehand and they will slide into place alot better.
once you`ve done one side, move the steering to the opposite direction to create the gap the other side and do the same again. once fitted, put the wire ties round the bushes to keep them in place, though to be honest, i don`t think they would come off anyway, given they `wrap` round the rack.
this is mine fitted and tied in place;

Image

i got my neighbour to rock the steering side to side when it was done and all the play had gone. i also drove it down the road and back and the steering is certainly sharper again, just as it was when i got the car, but obviously the play had crept up on me, so it was`nt noticed!
anyway, hope this helps ;)

That's some price for a couple of plastic washers , mind you , if it does the job i suppose :?

At least you have highlighted a possible problem if you get that old '' play in rack '' advisory ,

Good post mark. Am sure there are plenty of racks with play now, not least of which on higher mileage cars. I did check one of mine when you first mentioned this, but could not notice any play.
What confuses me about fitting these, is if this has the SPC jaguarsport part number, hen presumably its fitted to Xjr already?

they certainly are expensive for what they are derek, i agree, but when needs must and all that. i did read a post on another forum, where a guy had made a pair of shims that lock together from two halves and did the same thing, so if you have the machinery at work, i guess its easy!

what i`m confused about, is that JCP seem to list these spacers for the 93/94 cars only and blackcountryjaguar mention for the XJR. now what i`m thinking is, if it was an issue on the later cars and/or the XJR, why was`nt it more of an issue on the earlier cars? yes, there may be variations in the rack itself, such as the XJR, but surely they are all fitted the same way to the car, i.e bonded to the brackets. so what changed on the later cars, that they bought out these spacers :?
seems a silly idea to me in the first place, to `bond` a rack in place. why did`nt they just have locating pegs or pips moulded onto the rack, with locating holes or something in the brackets.

Hit the nail on the head there Mark, that's why I reckon it was a late thought out modification

Essentially any bonded material is just inviting failure. Vee mounts anyone?

crazy idea if you ask me, bonding stuff like this, especially those vee mounts. these things are pretty much all that holds that front subframe in place really.

Hey Mark,

thanks alot for this post.
I noticed a slight movement in my steering rack a while ago.
Tested and checked it at least ten times without result but my focus was on the track rods.

I will have a look at these brackets later on.

hi axel

your more than welcome, i hope it helps.
you don`t actually realise untill you do this job, what a difference it makes to the steering. as this bonding lets go and the rack starts moving, it creeps up on you and you don`t notice the subtle difference in the steering. since i`ve added these bushes though, the car is back to nice, crisp, sharp steering, which i had when i got the car, but had`nt noticed it disappearing!
the bushes are`nt cheap for what they are, but i guess its cheaper than buying a new rack ;)
