The 5.9L motor in my 98 2500 quad cab has developed a lower end knock. It's most noticeable on start for a few seconds but it's always there just much quieter. This truck has about 100K on it. My thought is a rod bearing but I guess it could be a main bearing.
Other than this the motor runs strong. We pull a 5000 pound trailer about 200 miles every weekend for several months. We're looking to possibly be pulling for longer distances next year.
Are there any reasons to not putting rod and/or main bearings in? Or is a short block the only way to go?
Thanks for any suggestions.
