At about 131,000km, I replaced the front unit bearings with some Raybestos ones as one of them was failing.
Now at ~153,000km, both have enough movement that it was noted at last rego check and I've been getting some squealing fron the left side when on right curves. So today I put the old one that was still ok back on the left side. Let's see if it fixes the squeal at least...
Of note, i also put the carpets back in the front & rear, (took them out to dry after all the rain last month). I think it was quicker swapping the unit bearing than putting the carpets back in!
