Volvo vs Sierra Universal Assembly

Postby steve & dot » Sat Mar 09, 2019 12:19 pm

I was getting some drive noise last year, more pronounced when turning left or right plus some vibes as the season went on. I replaced my gimble bearing last spring and aligned the shaft. I’m guessing my universal joints are going. 2007 4.3 SX-A. We just started a kitchen and bath remodel so I’d like to save time (although it will cost few more bucks) and buy the whole assembly and just swap it out. My question is- Volvo assembly or Sierra? The Volvo doesn’t have the grease fittings but the Sierra does. Volvo is $40 more. I guess I tend to lean towards OEM for parts but the grease fittings are a plus (I pull my drive every fall). Any fit or reliability issues with Sierra? Thanks.

How many hours on the engine? From my experience spend the extra $40 for the VP OEM ass'y. Most, if not all, rear drive cars haven't had greasable "U" joints for at least 20 years or more. My son has a 2009 Infiniti FX50S ( AWD) with 136,000 miles on it and still original "U" joints for both the front and rear differentials. Does your O/D have externally greasable gimble bearings? That would be the most important vs the U joints. My `1992 Python 24 Cuddy Cabin had the Merc 502 Bravo 1 drive with out any external "zerk" fitting and the gimbal bearing was the only thing that failed about every 3 years! Great job Merc, saved a drilled hole with Zerk fitting through the transom housing (guessing mfg cost about $2)and cost $300 to replace the non greasable gimbal bearing every 2/3 years!

Around 300 hours. Volvo’s gimbal bearings are sealed now. Thanks for you input Bob. I’ll go with the Volvo assembly.

I would say ditto and go with VP instead of Sierra too. ;)

Just a follow on comment = When you replaced the gimbal bearing last spring you would have been wise to replace the U joints at the same time as the lower unit was off anyway? Also, when you do the u joints/shaft do the drive and exhaust bellows, shift cable bellows, and sea water impeller and associated "O" rings/gaskets etc.
Good luck and enjoy your vessel knowing everything is serviced/replaced like new!
