Help. I don't know what broke

[Sam-Son]

Ok so I got the car back from the tranny swap no problem. Been driving it for about a week now without any problems. I'm driving around yesterday and I start to feel some serious vibrations through the shifter in 1st, 3rd, and 5th gear. Then when I'm accelerating in first and second I get a horrible thudding and clunking from the rear end. I don't really notice it in any other gears. but it seems like something serious. What's gone wrong?
Please Help

Guibo or the driveshaft carrier bearing.

Guibo or the driveshaft carrier bearing.

I thought it might be a guibo. But how could that break so quick?

Scares me from wanting to do my swap :/

who knows what sort of condition it was in ... it's a wear item; unless you put on a new one ... then I don't know.

they may not have set the center bearing preload correctly?

Forgive me but I don't know what this means

There are 2 bolts under it and 2 slider channels ... the whole driveshaft/center bearing can be moved back and forth to adjust the preload.

However, in your case, (if this is what we're suspecting), it sounds more like a case of it coming loose than not being set correctly since it drove fine for a week.

Hmm so can I continue driving it for a day or two until I can get it fixed?
