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