Hello we'll my cobra has 15k miles on it and the rear end is leaking... Anyone out there have tips, hints, advise on how to tackle the job? I have the IRS brace and I'm a mechanic so I have all the tools just not sure how to start the job. Is it necessary to drop the whole rear end or is it possible to do the job while the IRS is still in the car? Any help or advise would be great! Thanks in advance!
