I have a 98 with 15000mi. extended cab longbed and recently have developed a shudder at about 25mph. Take off and highway speeds are fine just happens between 25 and 30. Could it be the u-jpints or carrier bearing. Whats the best way to check these. This is my first truck with a 2 piece driveshaft.Thanks.

 

Auto or manual?
Does it shudder while coasting?

 

auto and no it doesn't
