Need U-Joint for 2006 V6 DOHC Cadillac SRX..maybe?

We have an 06' srx caddy with 95k on her. We've owned the car now for about 6 months and it's transmission shifts are very smooth and it hooks up nicely, although when you do hook up for sudden bursts of speed (changing lanes, pulling into traffic off of interstate etc. particularly at slower speeds, the rear end %26quot;jerks%26quot; and makes like a clunk or slam type noise like something's not hooking up right, for sure in the rear! I think passenger side rear. I was sitting in the back today and noticed the noise as I said, in the back, you can even feel it lock into place (whatever IT is?). I told an old timer mechanic friend and he said it sounds like a U-Joint? He said they are around the drive shaft and go to each wheel. He noted that if I crawled under the car and tried to manipulate the joint, that it shouldn't move at all, if it does, then we may have to disconnect the drive shaft and replace it? I've done car repairs with friends but never any suspension joints or drive shafts,etc. Shocks, brake systems, minor engine stuff, but I figure I'll have my mechanic friend help me. I want to know 1) what is a U-joint

2) Hearing my story, does it sound like a U-joint problem?

3)how can I look one up online?

4) and lastly cost (est) and how hard is it to change one?



We are planning a trip up north and just had to replace the battery to an Optima because the stock battery died every day. We have the fully loaded version with the panoramic sunroof, power lift gate, Navigation, heated seats, 3rd row power seat.....power power power, I had to change that but otherwise it's a great vehicle! It's the pearl white and we have amazing payments on it, got a very good deal. This is our second srx and we have been nothing but happy with them! Thanks alot!Need U-Joint for 2006 V6 DOHC Cadillac SRX..maybe?
1. A U-Joint is a universal joint, in your case, probably only 2, on either end of your drive shaft that will swivel and allow the driveshaft to spin straight while the axle is moving up and down with the bumps and dips in the road.



2. What you describe could be a U-joint, but the ones I've heard are more of a clank than a clunk, with a metallic sound.



3. You can look one up online by typing %26quot;u-joint picture%26quot; into your browser



4. They are not a real easy thing to replace. You probably should get a repair manual for your car at a local auto parts store (about $20.00). You can read the step by step instructions and see if it is something you want to try. The cost is probably around $25.00 each.Need U-Joint for 2006 V6 DOHC Cadillac SRX..maybe?
Quick u-joint check. When shifting from d to rev and back, you'll hear the clunk. BTW, don't ever shift into D while the car is still rolling backwards. Bad for parts. Keep foot on brake when checking u joints this way. Also, try manually downshifting car into 3rd and see if clunk is there. Maybe the clunk you hear is the tranny downshifting. Did u change fluid every30,000? oops.
