    Control arm bush wear is a matter of distance, not years. On my D3 they lasted maybe 100k. Replaced with two after market types but went back to originals for the silent compliant ride. The Poly ones in particular were noticeably more harsh.
    As others have said, they're a consumable on these vehicles.

    I find it amusing, the Red Bull (TR once again tells someone their suspension is worn... Those bushes in the photo show no signs of leakage - so its highly unlikely they have failed yet.

    I took a fully rebuilt vehicle to TRB after fitting a full race spec package to it. All I wanted was an alignment done (they were just around the corner so convenient). Came back to a 'diagnostic' report stating I needed new shocks, my bushes were worn and spring had sagged
    To say I took the shop manager to task was to understate it - I never paid that invoice


    Vibration / Pull over 85km/h is more likely to be tyre imbalance.

    Thanks everyone for your feedback! I've opted to go for OEM rubber replacement this week.
    Will likely buy some AT-205 re-seal to spray on other bushes, mounts, etc to prolong life.

    I've had to replace bushes on a 2007 Ford Focus with ~25,000mi on it at 7-8 years old and a 2013 Chrysler 300 (+ball joints) at ~250,000km on it also around the 7-8 year mark. No evidence they had been replaced before my ownership on either car. Combination of distance, age, environment and how hard the car's life has been I guess.
    The Disco 5 is currently around 97,000km and 5 years old.

    Yeah, sadly, I have little trust of the motor trade too.
    I was there helping out when I had initial wheel alignment (on a new laser-based machine) and we definitely had all the numbers looking good. What confused us at the time is that they weren't that too off spec in the first place. Also had wheels balanced (albeit just at Costco) just days before that alignment. But still, the car pulls and vibrates and has got worse over the weeks since.

    It was after this initial balance & alignment round I took it to the local Pedders who showed me under the car the state of the bushes and how easily they allowed a lot of movement - see vid in original post.
    You're right, the bushes haven't totally failed yet - no noticeable knocking over bumps or rough roads, but degeneration has progressed to a noticeable tracking problem, accelerated uneven tyre wear and vibration because of uncontrolled movement allowed by the aging rubber bushes.

    I should take a video when the new front bushes goin in mine soon... hydro bushes have so much flex even new...

    That vibration is a bit of an odity, and by now tyres are probably showin signs of it - so it will continue to amplify from here on.. you may need to rotate F-R and see how you go.

    Was the vehicle set to tight tolerance mode for the wheel alignment? If not then the alignment may be out which can cause tracking and balance issues.

    Rotation was done with balance at Costco days before the alignment.

    Yep, tight tolerance mode was activated. We knew before, but even the new alignment machine displayed the procedure after selecting the vehicle that was on the ramp - clever stuff!

    Just came across this helpful PDF about hydraulic / fluid filled bushes: https://www.pedders.com.au/wp-conten...-bushes-v3.pdf

    Angry

    So after all that, the bushes replaced, 2 wheel alignments and 2 balances and a major service replacing all diff fluids, transfer case fluid and a gearbox service, the car is still vibrating and pulling left
    Not discounting the possibility of defective tyres, any ideas what it could be?

    Its time to start moving front wheels to the rear to determine whether there's any change in case a rim is buckled.

    Is either rear brake hot indicating binding?
