Pre-MOT Inspection Checklist for London Taxis Int TX4 Bronze Owners
These checks follow this London Taxis Int TX4 Bronze's own most-recorded failure strings, starting with what a tester is most likely to flag on a London Taxis Int TX4 Bronze.
-
the suspension joints — “pins and bushes pin or bush excessively worn”
With the car parked on level ground, rock the top of each front wheel in and out while someone watches the suspension arm. Clunks, or rubber boots split and greasy, are what testers record here.
-
the coil springs — “coil spring fractured or broken”
Look up inside each wheel arch with a torch, all the way round the spring. A snapped spring usually breaks at the very bottom coil, where a quick glance will not reach.
-
corrosion — “integral vehicle structure condition corroded to the extent that the rigidity of the assembly is significantly reduced”
Look under the sills, around the jacking points and where the suspension mounts meet the body. Flaking, holed or crumbly metal fails; a brown stain on sound metal does not.
