90 B2200 Driveshaft

I have a 1990 B2200 Ext Cab 5spd. I have a severe vibration at speed. I can hear a squeaking when I back up that I believe to be u-joints. 2 of my u-joints are staked in. The cost for a driveshaft is around $400.00. I have found a website http://www.arizonadrivelines.com/u-joints_staked_type.htm that says they have replacements u-joints for my truck. I just wanted to know if anyone has tried these and if so any problems I should be aware of. My cost would be about $125.00 this route.
Thanks

I will go ahead and let people know for future reference. I went ahead and bought the u-joints and took driveshaft to a garage. The mechanic said he could get the old ones out but what was I going to do for u-joints. I showed him the new ones and he was very interested in where I got them. He was sending everyone with staked in u-joints to buy the $400.00 rebuilt driveshafts. To make a long story short the u-joints have been installed and work perfectly. Total cost including install with 3 u-joints and carrier bearing was just short of $200.00.

Oh man. I just spent over 400 for a mechanic (at the dealer - big surprise!) to replace my carrier bearing. I notice that I now have a little "slack" in the driveline when I decelerate and there's an accompanying 'clank' sound. I think it might be the u-joints (?). I wish I had had them both done at the same time (and for 200!). That's cool. Thanks for the post.

Just did my drive shaft using the replacement u-joints from the same site. They worked. $25 per u-joint and $65 for the center bearing support. Now it's tight and quiet.

yeah you can get those u-joints anywhere, i did mine twice now, (had a horrible pinion angle for a bit) so i dont know what your mechanic is talking about
