Universal Joints

[ff-racer]

I have a 2004 Lt Trailblazer with 80K miles that the universal joints in the rear driveshaft need replacing. The Oem parts are $150 more than aftermarket.
Is it worth the additional expense?

Thank you in advance.

What is the difference has anybody explained the discrepancy, I'v used AM, with no issues so far.

Well, I went with the aftermarket ones. Time will tell. Seems like there is no longer provision for greasing these new ones either.

one w/ no zerk fittings, but has a lifetime warranty $16.99 each

the cheaper version w/ a zerk fitting but only has a 2 year warranty $11.99 each
