for the price i dont know but if u want check forsure just take your jack & raise the front up & go under it & u should be able to tell where its comin from if u cant just get u a can of carb cleaner & spray all the grease off then drive it some & look at it again then u should be able to tell pretty easily u may just have to have a new boot or just an axle which would still be better then gettin a rack just so u know what i'm sayin is it might just be the grease from the axle gettin on the rack makin it look like its leakin & when u raise it up pull the parkin brake & put somethin behind & in front of the back wheel so it doesnt roll & it doesnt hurt to put somethin under the car to catch it if the jack fails doesnt hurt to be safe hope this helps ya
