New to forum, and need a few answers
 

Hello, my name is Zack. I am almost 18 and live in Springdale, Arkansas. I have a hunter green 1998 Blazer. LS with every option except leather and sunroof. It is a 4 door 4x4. I just bought my Blazer two weeks ago and can't stop driving it. I leave my Mustang parked in the garage now haha. This is the third Blazer we have had in my whole family, my cousin has had a 97 and a 99. I hope to get many many miles out of the Blazer before it is time to move on.

Now for a few problems. I have a couple of drivetrain clunks. One that seems to come from u-joint on the rear differential and one from the transfer case when switching in and out of 4Lo which I think is a cv joint. I also have a gear oil leak coming from the front diff where the cv axle meets it. How would I go about replacing the u-joints and cv joints? I might as well replace all the u-joints and cv axles. (the Blazer does have some miles on it)

Also, I have an oil leak coming from the lines going into the oil filter. It is not bad, just a few drips here and there. How difficult is it to replace those lines/hoses?

And, there is a slight tick. Not many people know what it could be but maybe someone on here might have had it happen to them. The Blazer holds good oil pressure and runs smooth. It ticks when its idling or decelerating when it gets warm. It goes away on acceleration. Anyone know what this might be? I know somebody whose Olds Bravada did this but could never figure it out since it came and went with his car.

Hope to get some answers. I gotta make a trip to St. Louis in a few weeks and need to get the blazer in tip-top shape. Thanks for reading and have an awesome day!
