Could lift cause damage to front axles, axles seal, and therefore differential?

    So, as most of you may know... I have a leaking front drivers side axle seal. This is the second one in 6 months.

    I brought the truck back to the local dealer yesterday morning.

    According to the dealer, the reason for my failing axle seal is due to excess angle of the front driver's side axle. Probably from my lift. Which has caused excess play in the axle which has not only worn out the axle but also the front differential

    I can't imagine this was caused by the RCD lift, since the cv angles are perfectly flat. Therefore the lift they are thinking of must be the previous lift 3" suspension lift. Has anyone heard of this happening?

    So, now the truck is gonna be at the dealer til atleast friday getting...

    a new front differential and front axles! :eek:


    Anyone else experience front axle seal problems?

    hmm... well they are replacing the front diff and the axles... this is what the service mechs said caused the problems... but I dunno, it sounded fishy, maybe the cv's but the front diff....

    whatever it is... theaxle seal keeps failing, and they say this is due to excess play in the axle caused by the lift, and this has worn out the front diff.

    I've only had the RCD for a month and the last seal failed with the 3" lift... so I can't imagine it is the RCD

    probably not caused by the RCD lift though... the seal failed the first time about 6 months after my first lift, and failed this time about 6 months after that...

    well I can't imagine any other way for the axles to have excess angle... I dunno, but all I know is that my axles are very flat right now with the RCD kit.

    Maybe the dealer doesn't know whats up and this is a best guess... its probably a manufacturing issue with Toyota.

    I have noticed that the front axle seals tend to fail quite often... I did a quick search and found about 5-6 thread about failed axle seals... so who knows.

    The dealer is gonna replace the entire diff and axles so... whatever :mad: hopefully, this solves the problem.

    while I love my Toyota... I have notice a severe inconsistencies in quality

    I responded in your other thread. As for the mud, Did you get right up there with the pressure washer and blast the mud out off the front diff and DS's?

    okay

    I can't be sure that I got all that mud out but I was for sure washing the diff... I spent 2 hours pressure washing all the mud out from the engine and under the truck. matter of fact when I was recently inspecting the diff there was no mud on it.

    Welp...If you got that close, odds are, you blew the mud into the seal.

    Im guessing the tech didnt clean the seal surface very well, or it was scored.

    well, I'm not saying the techs know everything... or always tell the truth, but they are the ones telling me the failure was caused by play in the axle which was in turn caused by the excess angle of the axles due to the lift.

    If that were the case, and asuming you had your lift at 3", there would be a shit load of people with the same issues.

    tie rod ends fixed... everything is kosher now...

    I still don't know how the axle seals kept burning up

    Dealer: Lift, axles were at severe angle... damaged axle and front diff
    Chris4x4: Bad seal, mud in seal (x2)

    or damaged during RCD install...
