Just to add some more to the mix though (might be worth checking this?)
I once had a Citroen Van which had a weird clicking/ticking noise, used to drive me mad at low speeds,
Only ever did it when I was alone in the cab, whenever a mechanic got in the passenger seat for a test drive it stopped, it did it when the van was loaded or unloaded (3.5t van)
I had it in loads of garages (I regularly stopped when out on the road to have it checked as I passed a garage because it drove me insane, sometimes louder than the radio, sometimes just an annoying tick tick tick) but nobody ever figured it out, had it jacked up, on ramps everything you could ever think of.
the wheel bolts were always tight whenever a garage removed the wheel to check the disks/suspention/cv joints etc etc.
In the end I had a puncture fixed and the mechanic torqued up the wheel bolts, no problems.
the next day the van lost the same wheel on the m60 (front NS, 40 mph in heavy traffic, was very scary!)
but after recovering the wheel (about 1/2 mile down the hard shoulder) and 1 of the 5 lost wheel bolts I got some new wheel bolts from Citroen, turns out in the past the original bolts had been overtightened which ruined the threads, they tightened easily when they were put back without a torque wrench, but were constantly slipping through the threads and clicking on every revolution of the wheel.
I would never have figured it out had the garage not torqued the bolts to the correct setting.
If you have locking wheel bolts it might be worth comparing the threads on you unused bolts (in the locking wheel bolt box usually) to the threads on the bolts holding your wheels on.
TBH it's probably nothing to do with this, but I mention it as an example of the weird stuff that sometimes happens (particularly to me!)
