Was under the car today trying to find the cause of that elusive tinging noise and noticed these two things, firstly, this bush...seems cracked/perished to me, whereas on the other side it isn't. Could it do with being replaced?

Secondly, in the yellow tube which sits between the two torsion bars, I have come across this little ridge, or outwards dent type thing, not sure if its just rust caused it to bubble or is there a problem?

Cheers
