    you may want to price name brand replacement bearings and u-joints at several on-line sources and look into DIY videos
    while your there CHECK out the brakes, pads, rotors calipers.


    If one rear wheel bearing wore out, its time for putting the corvette up on jack stands or a lift, and careful disassembly ,
    of the related drive train and suspension, bearings, too carefully inspect,
    repack or replace the other three wheel bearings and replace all six u-joints,

    logically the components have all traveled the same distance, if they are all original components thus have similar wear induced


    yes it sucks and its more work, yes it costs more money,
    but doing maintenance now
    sure beats the crap out of loosing some critical component under stress at speed
    where it at best leaves you stranded in the boondocks,
    or at worst causes a serious accident.

    youll occasionally see someone post a maintenance schedule that suggests component replacement at (XYZ ) mileage,
    stress is cumulative and the way you drive has a huge effect on component wear,
    you might find a buddies corvette has good looking u-joints at
    100K miles
    (they should be replaced at 100K just for peace of mind)
    and yes you might find your on
    your third complete set already replaced,
    BRAKES ,should also be inspected every few months or every 15K miles,
    yes it sucks and its more work, yes it costs more money,
    its still preferable over a major un-expected drive train,
    or suspension component failing.while your at speed.

    On the C4 Corvette, there are several maintenance items which should be attended to on a regular basis.

    whenever the less frequent items are attended to.

    Every 300 miles or every week
    (whichever comes first):

    Check Engine Oil level
    Check Brake and Power Steering Fluid levels
    Check Engine Coolant level
    Check Windshield Washer Fluid level
    Check Tire Pressures and Condition of tires
    Every 3000 miles of every 3 months (whichever comes first):
    All of the above plus:
    Check Automatic Transmission Fluid level
    Inspect the Engine Hoses

    If Manual Transmission, Change Overdrive Fluid
    Drain, Flush and Refill Cooling system
    Inspect Evaporative Emissions system
    Replace Spark Plugs
    Inspect Plug wires, Distributor and Rotor
    Check Timing and Adjust as required
    Check Shock Absorbers for leakage
    Every 100,000 miles or 6 years (whichever comes first):
    Perform ALL of the above steps plus:

    Inspect Steering System wear indicators
    Inspect Exhaust Manifold for cracks

    Nice checklist Grumpy.

    C4 Corvettes do not rust.
    Non Issue.
    What is steel is galvanized steel and then painted.
    All fasteners are thick cadium plated too.

    Cooling system flush Grumpy.
    Should be done every 2 years.
    Prestone regular Green antifreeze you buy now is supposed to last 5 years.
    Noticed it breakdown on 5th year in my 87 Vette.
    Cleaned it all out with Evapo Rust Thermal cure. Great stuff.
    Prestone back in .

    May switch try Diesel Truck Shell Rotella Antifreeze this fall in all the cars & trucks.
    Stuff is superior to any auto anti freeze I have seen.
    Cost about the same.

    Evans still too expensive.
    Spring a leak there is $200-500 bucks on the ground.
    Junk & money gone for good.
