Debbie Campbell... hello,
I know this will sound a wee bit odd...
Let me stall you a little bit... because unless you take your vehicle off road (even if you do) there's a GOOD probability
you are looking for a fairly inexpensive problem if you get to it NOW... (Catastrophic
if you ignore it).
But if you care about your vehicle(s) as much as I do it might make sense right now. Life's early poverty dictated I fix things myself... (or walk).
Later life: experience and cynicism (after the "professionals" broke at least two things for every one they fixed)... I continue (happily) to fix things myself.
There are SOME places to get information in cyber-space... some good ... MOST pure HOKUM
If you want the VERY BEST INFORMAION the BIG secret is
the FACTORY+WORKSHOP+MANUAL... 3 books
(eBay, used $150 ish).... See the eBay URL (below).
A little shopping = better deals but Volume 3 is hard to come by... CDs are also available (worlds cheaper)... but I like having the pages (copies) at my side as I work.
makes some of the very best... (note: Volume 3
has wiring... lots of folks leave that out... but after 50 years of steady electronics... one thing I know for sure: its ALL BATTERY & GROUND (notwithstanding contemporary "wisdom" to the contrary))... all those on-board-computers make it all quicker, better, faster, easier!
And... They have an APP for that (Bluetooth OBD
((the goal for that is the same as a GOOD WINE... the best price!).
Right now.. you don't care about any of that...
Transfer cases + drive-lines, shafts, joints are covered EXTENSIVELY in Volume 2
If you have a hoist or a REALLY safe way to get under your vehicle... Your description logically puts it into the front drives.
Or... ask your local gas/service station if you can watch them give it a FULL-LUBE JOB... If they find something
(& their prices are NEAR RockAuto: CV = $114, U-joint = $16)...
The clatter... means it could be far enough to be shinning metal at the flex joints... or producing IRON OXIDE (CHOCOLATE/RUST color)... Those are the big clues. Failing to see any of that..
You are going to have to check for FREE-PLAY...
Every "U" joint or "CV" joint you have should be really snug.. any slack can be YOUR problem.
It may take you and an assistant to play the wheels back and forth... until you find the offending joint... (these troubles usually travel in pairs).
Sorry I'm so chatty... Comment me back if you've more questions.
Be safe... Chock
