The inner boot in both side closer to diff where wrap around the shaft is leaking the clip is good and boot has no tear in it but I guess they just leak after while the right side has more coming out of it than left side I could see there was some old grease built up but it seems it got worst when I give it the 3 inch lift I have no idea how much grease it has lost so I took it to Lexus dealer they want $57.00 for each boot and $500 for labor for each side to replace it for grand total of $1200.00 .is that normal cost to replace these things? they told me in order to fill the boot with grease when they take it a part they have change other parts that is why it cost that much i never taken one of this thing a part but $1200.00 does not sound right to me i have bad feeling they are giving me the grease.
