Welcome along,
for the clinking (lf on the rear) check the splines on the axle/hubs too, get some decent grease on there as that's common.. There is a guide on here somewhere but it's simple I belive it just involved taking the split pin out, count the rotations to loosen - but don't remove the hub nut - just enough to pull it away, then apply your *suitable* grease using a small paint brush, then reverse to re-fit. It stopped some chingling noises/clunks at low speed for me
