If you install them correct they will not leak.

Here is what i do. Take the block where it sits up against the rear and measure the recess where the factory bearing lip goes into the eliminator, if this is say for example .400" deep when you cut the factory lip off cut it so there is .300"-.350" going into the c-clip eliminator

What this does is properly locates the c-clip eliminators, works very well as i run them on the street with no leaking

If you cut the lip off like they say you rely on four 3/8" bolts to align the c-clip eliminator and stop it from walking

With the lip you have part of the rear centering everything up correctly and the c-clip eliminator will not walk and leak
