Paul Posted November 21, 2002 Share Posted November 21, 2002 Hi all, Wonder if anyone has had this? I seem to get a 'knocking feeling' through the steering when on full lock, in reverse? It works out at about one 'knock' per revolution of the wheel as I reverse slowly, and tugs slightly each time at the steering (feels like when a cv joint goes on a front wheel drive). I wonder if it might be a caliper not freeing properly as it happens when it's been parked for a while. Tyres look ok, nothing in them, wheels fine too. Any ideas? Cheers, Paul.

Paul Posted November 21, 2002 Author Share Posted November 21, 2002 Not many takers on this then? What about the fact that the traking is out, n/s front worn on the inside.I'm getting this sorted but is there any way this could have this sort of effect? Or shall I put Neons on and a thing to make flames shoot out the exhaust will this cure it?? Help! Paul. Quote Link to comment Share on other sites More sharing options...
lust2luv Posted November 22, 2002 Share Posted November 22, 2002 If it's any help, it sounds similar to a problem discussed a few months back. I think Flip was suffering something like this? Try a search. Quote Link to comment Share on other sites More sharing options...
Suprash Posted November 22, 2002 Share Posted November 22, 2002 I have a simila problem, there have been a lot of discussion on this sort of problems, would suggest a search of old thread, I know I brought this up recently as well. Quote Link to comment Share on other sites More sharing options...
Christian Posted November 22, 2002 Share Posted November 22, 2002 It's not the LSD causing a tyre to skip is it (because one is travelling much further than the other)? Mine does that on full lock going forwards. Quote Link to comment Share on other sites More sharing options...
Paul Posted November 22, 2002 Author Share Posted November 22, 2002 Cheers lads I have looked at older threads and it seems it could be something to do with bolts under the front needing to be tightened? Cristian, an idea but because this is at low reverse speeds, just higher than tick-over, then I doubt it, also it is pulling slightly on the steering and seems to be a front end thing.Cheers anyway mate.

Chris Wilson Posted November 22, 2002 Share Posted November 22, 2002 A lot of MKIV's do it, I am too tired to type it all up, but basically it's a suspension geometry thing that only shows in reverse a side thrust is imparted on the tyre tread in reverse, on a lot of lock, the tread deforms so far, then "jumps" and releases, a sort of skip. The phenomenon sometimes appears worse on none stock wheel and tyre size and offset. This is the common cause, it could be something worn or a none stock tyre size or a lowered car having the tyre foul the top of the front arch liners, too. That should be visible with the front jacked up and a torch, you'll see the rubbing marks. It's not a fault if it is the geometry, basically the suspension and steering kinematics are designed for going forwards :-) Quote Link to comment Share on other sites More sharing options...
Paul Posted November 22, 2002 Author Share Posted November 22, 2002 Chris, I've got stock wheels and tyres although the front two need replacing due to wear on the inside (one more than the other). Could what you describe be made worse by the tracking being out which it looks like it is? What I'm worried about is replacing two front tyres and then scrubbing the insides because I missed something else, what about a full geometry check, would you think this is enough to put my mind at rest when having the new tyres fitted? Thanks, Paul. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 22, 2002 Share Posted November 22, 2002 All MKIV's scrub the insides of the treads, it's a function of their geometry and weight, but if it's excessive you could get a full geo check done. I very much doubt your noise is tracking or geo related, a good 80% of the cars seem to do it, even those with just completed geo set ups. More likely tyre make related.

Steve Cargill Posted November 23, 2002 Share Posted November 23, 2002 Paul, there's been a few threads about the loosse front suspension bolts recently, but I don't think that will cause the noises you describe. The bolts are a creaking, most noticable at parking speeds and NOT related to wheel revolution. I'd get the bolts checked though, but probably not your problem. Do a search for "I don't creak anymore" by me and a later thread by vodoo (or however he spells it) If you've got UK brakes when you touch them in reverse they clunk - J spec don't do that.

Terminator Posted November 23, 2002 Share Posted November 23, 2002 Steve I found the floating callipers of the jap spec brakes made far more noise on change of wheel rotation direction than the UK ones. I get no noise atall form my UK's. I think it may depend on how free the sliding callipers were, my Jap brakes had only done about 27K miles so were pretty free to move.

Steve Cargill Posted November 23, 2002 Share Posted November 23, 2002 Phil, my J spec were silent, I get a loud clunk as soon as I touch the brakes in reverse - checked it out and it's normal apparently... Seems each car has it's own little quirks!! Quote Link to comment Share on other sites More sharing options...
Terminator Posted November 23, 2002 Share Posted November 23, 2002 I'll watch out for that, may be I need to be going faster in reverse:D Quote Link to comment Share on other sites More sharing options...
ninja_eli Posted December 17, 2002 Share Posted December 17, 2002 Just to say that I too get this sound, and I had the geometry and tracking checked. Everything was A okay. Its a horrible noise, but nothing you can do about it! Regards Quote Link to comment Share on other sites More sharing options...
Paul Posted December 17, 2002 Author Share Posted December 17, 2002 Well, mine seems cured now, since this post I had a full Geometry check/adjust and also got them to tighten the bolts mentioned. They set up 'the machine' for the Geometry, took the readings then tightened up the bolts (not much play in them though) and this had brought in some of the front settings just by doing this on it's own! Also they fitted two new Goodyear F1's to the front and I've not experienced the 'knock' since I suppose it could have been either the 'bolt' issue or the fact the geometry was wildly out, who knows? I'm just glad it's now sorted. Paul Quote Link to comment Share on other sites More sharing options...
