Had a health check done on my car by MB Romford when they fitted the new cats, which they've just sent me. They said the rear brake pads were beginning to get low but noted the minimum wear sensor was not yet activated. 4,000 miles later the minimum wear sensor is still not activated. How long have I got before these need doing? They also noted the offside track rod end had some play and recommended replacement of the pair. 4,000 miles later I haven't noticed any knocking. How long have I got before these need doing? Finally they noted that the rear prop shaft coupling is beginning to crack. I haven't noticed any clunks when pulling away after 4,000 miles. What's the consensus on this one? How long have I got before this needs doing? I'm hoping to spread the cost of attending to these problems over the next three months as my wife's illness is a continuing drain on finances. Any ideas as to the order of urgency I should apply to these items?
