Hi, I just bought a Grand Caravan 2008 and had a weird noise in the back. I finally managed to find that rear bumper (metal part) is not fixed. My guess is previous owner had a hitch and they removed it without putting back the bolts.
Anyone knows which size and lenght I need to buy???

Thanks!

 

Finally found the answer. If anyone needs to know bolts are 7/16 x 1.5inch, don't forget to put a lock washer to be more safe!

 

I have the same problem on a different van. Just bought an 02 grand caravan, strange rattle noise in back, previous owner removed trailer hitch, no bolts left to hold the bumper in. What size do I need to get?

 

I don't know for 2002 model, but you can go to your garage and ask them. I ask my garage when they changed the tires and they didn't charge me for them!
