It will be the steering lock stops, happened to me when I went from 235/85 up to 255/85 size tyres.
If I remember rightly it’s front axle up on stands, loosen lock nuts of the steering lock bolts. (WD40 a day before) Adjust them so that they clear the radius arms on full lock each side. You have to leave a margin because when under load the gap will lessen with weight back down. A pice of wood is an ideal guide between tyre and radius arm. Something like 20mm sticks in my mind. You can do it on the ground too but involves moving it around back and forth. (Make sure handbrake is on  )
Once adjusted lightly tighten the lock nut again to set the lock stop bolts in place. As mentioned it is a 17 or 19mm spanner if i remember rightly. It’s a faff more than a hard job, when I did mine I adjusted the lock quite wide which meant I had a wide turn turning radius a little too much really. Since then on servicing they’ve been adjusted a bit closer and I now have more steering lock but no tyre to radius arm contact. Once adjusted for wider they can stay at that, because even if you went back to narrower tyres they would be an issue. You’d only gain a little more steering lock that’s all. You can get it done for you, it’s a relatively easy job and shouldn’t cost much at all. Personally I’d use Halfords for a little job like that or headlight adjustment. They do that kind of thing all the time and charge very little. A dealer or other large enterprise is more likely to see it as a money spinner and develop a job out of it. LR Dealership didn’t even adjust my headlight beam properly I requested, I knew it wasn’t set properly after and took it to Halfords instead and they tested it and did it for me instead and they said it wasn’t to MOT spec and cost £15 1/3 what LR charged and didn’t do properly. Been fine ever since and never had an issue, just goes to show that main dealers not only over charge but often are incompetent too. Then there was the time I got the clutch replaced at main dealer and came back with the main Earth strap so loose it was tightened up by hand and had the lights light up on the road like an Xmas tree due to Earth fault so dash flashing and indicators, and all sorts such as that. $W33T $0U7H3RN $UG4R 🇬🇧🏴🏴🏴🇮🇪🇺🇸⛽️🛢️⚙️🧰💪 |

Just as additional info to Steve's post above, on the Puma remember that the nearside lockstop sets the clearance between the back inner edge of the offside tyre and radius arm, and the offside lockstop sets the nearside clearance (Series models were different, the offside set the offside and nearsdie the nearside which made it a little easier to adjust).
It is also worth remembering that as a result of the adjuster being on the opposite side to clearance it is setting, adjusting the tracking, which changes the length of the tie-rod, will upset the lockstop settings. When setting, I normally use my fingers as a thickness gauge - if the fingers of a flat hand fit between the radius arm and the tyre, generally the dynamic clearance will be as tight as you want to go. Alternatively use a calibrated piece of wood, calibrated to be the thickness of a finger, as a gauge. |

Thanks for all the input guys-the knowledge on here is impressive!
Going to leave this little job to professionals so it’s fully on the road asap. |

Did this get sorted? Would be great to get feedback on what it was in the end.

Have an answer for you on Tuesday when it finally goes into local garage. Getting a slot anywhere at the moment seems to be a nightmare and didn’t want to drive it too far (and do full locks) as a YouTube video I found showed what (if it is the steering stop locks which I think it is) damage could be done.
Watch this space! |

i intetionally left mine a little too far so i can get max lock. its trivial to avoid it when manuevuring and you only get the issue when travelling at parking speeds. its not like you lock it over at 70 is it lol.

Remember that you will (or at least, should) fail the MoT if there is any contact between rubber and metal.
I used to wind the screws out a turn before the test and back in afterwards! |

So an update-all fixed.
You guys were on the money as it was the lock stops. Taken out for a drive and no more grinding etc. breezed through MOT apart from advisories of surface rust on brake pipes. One thing I’ve noticed taking it down B roads is how different the driving characteristics are now! Before I could Chuck it into corners and basically grip it by the neck (as we all do), now it’s a very different beast. Granted the Bond film ones were on 37’’ tyres but even with 35’s fair play to the stunt drivers ragging them on the roads. May have to update the brakes at some point. |
