Sppedo wobble is usually caused when the cogs inside the speedo dry up - A dribble of 3in1 oil can help. Wobble can also be caused by a kincked or damaged cable. As your mile reading has now given up I suspect that the cogs dried up and the teeth have now stripped so it is time to source another speedo. There were never any speedos for 175 tyres so I would look for one around 1350 tpm to get the best reading and compare it to a satnav to be 100% sure....

Grease WILL NOT work - This is a clock mechanism not a wheel bearing !!!!!!!
