Description Reviews MINI Transmission Outer Axle Seal (Driver's Side) for all R52/R53 Getrag 6 speed units and early Midland R50 units. This seal fails from time to time due to heat and dirt. As the cars get higher in miles, the seals just wear out. If you're planning on taking the axles out it might be a good one to have on had because your local parts store will not have this seal. If you see leaking from this seal, it's time to replace it. Running the transmission with low fluid could do lots of damage. If you're planning to put race axles in you might want to just replace these as it puts the new seal into a different position and a leak is likely going to start once you have it all back together. Do the job right the first time. This is a brand new seal that is MINI OEM and is 40x62mm in size. You only need one because the other side is a different size. This could also be a good time to flush the transmission and put some good quality fluid into it. You will be surprised how much difference it makes! Fits: R50 Cooper Midland Trans up to 07/04 Outer R52/53 Cooper S Outer
