my dryer is making noise and is also burning my cloths in the seal behind the door. it seems that the tumbler is sagging down and that it might be a bearing problem but if somebody knows different it would sure help

Sounds like your front glides are shot but may also be a problem with the rear bearing.
Note when removing the rear bearing keep a close watch on the ball bearing (Item 1205 in Section 3) once released it likes to play hide and seek.
You will have to open it up and check to find the cause.
You may as well also check the belt, idler wheel etc. for wear and slop.
Clean the rear bearing, check it for wear and re-grease it using a hi-temp grease.
Give the interior a good clean including the blower.
Also a good time to clean and check the vents system.
Basically you are doing an overhaul on it so that with any luck you will not have to open it up again for a while.
