Hi folks,

2004 100 series - I've had replaced:
  • Steering Rack & track rods
  • UCAs
  • LCAs
  • All diff bushes
  • Front bearings
  • CVs
  • Droplink bushes
Had alignment done by a garage after.

Above were all brand new OEM parts, but now when turning on the spot or at slow speeds, e.g. below 10-15MPH, I notice a single sort of thud that I can feel in the floor.

I've had the suggestion that it could just be torsion bars, but it never had this issue before having everything replaced, so I'm keen to get this sorted out as I don't want it to cause me any more issues on new parts.

Has anyone got any suggestions of what I can check?

Thank you!
 
Does it only happen when the wheel is fully turned or do you feel it right as you begin to turn the wheel? Did you replace that stuff attempting to fix the problem or did the problem start after some repairs? When did the problem start?

The lower control arm has little stopper things on the lower backside. Mine weren't adjusted correctly at one point and now and then with wheel at full lock it would sort of contact and making a metal popping noise.

You could take a quick look under there to see if it looks like they have been getting contacted / show signs of wear. Otherwise just as guessing game for now. Maybe wheel bearing preload or something not torqued down all the way from recent repairs?

  • It is a bit inconsistent, but will happen not long after turning the wheel sometimes, and other times 3/4 of the way to full lock.
  • The problem started after repairs, it had everything replaced in one go as all the bushes, CVs etc were all needing replacement, and immediately got it's tracking done. I got the car back and noticed it did this but haven't yet had chance to get it looked at - plan is to in a few weeks.
  • Thanks for the suggestion ref. stoppers, I'll take a look
  • I've been assured everything is tight and we've had more work done since then and nothing raised, and the bearings don't have any play
 
I just went through the exact same thing, and turns out the dealership did not tighten the cam bolts all the way. This was creating a racket upfront, so something to check.

The second thing I found, was the sway bar popping over bumps. I did not torque down the Sway bar LCA mount, causing the eyelet to bounce around a little on the bolt.

Thank you, I'll check these!
 
Following.

I have a similar issue, can’t find anything loose. I’ve removed the front sway bar as well so that isn’t causing the sound.
