SOURCE: cambelt installation problems on a subaru legacy 94
There is a belt tensioner on the front of the engine block that needs to be taken off and compressed(use a vise if possible) you can use a small allen key or something of similar size to lock piston intoethe compressed position . Then reinstall. I am assuming that the belt routing is correct but the compression of the tension cylinder needs to be done for proper belt tension.

Your '93 Legacy was one of the first cars to provide ABS as standard. If your ABS is activating, you'll feel a fast pulsing feel when braking, is that what you experience?
If it's more of a brake pedal movement that changes frequency with the cars change of speed, and when moving slowly it feels slower and more pronounced, you likely have a warped rotor.
An ABS issue should be checked out by a Subaru mechanic. If it's the rotor, then the offending rotor will have to be machined or replaced. If you can identify the rotor that's warped (with the car on stands, rig up a steel ruler so that it touches the rotor, and spin the wheel by hand. If it touches intermittently, then the rotor is warped) you may be able to remove it yourself (buy a workshop manual for instructions) and bring it to a brake shop and have it machined. This is far cheaper than they doing the whole job.
However, if you're not comfortable with these suggestions, then have a brake shop do it for you. This is an important safety device (obviously) and worth the money to have it done correctly. Early Legacy's are pretty much bullet-proof and last forever, so the investment will be worthwhile.
Hope this helps.

What issues are you having? Is it jerking while making tight turns (typically u turns)? If so, your clutches for your all wheel drive are bad or your duty pressure solenoid located in the valve body is bad. This can happen if something hits the transmission pan and hits the solenoid.

there is a rocker switch on the top center of your steering colum that may have gotten turned on

check the idle air control unit. its on the passenger side of the intake manifold. to remove it there are 4 10mm bolts and you can leave the coolant lines attached. Get a new gasket so it will not leak when reinstalling. Clean the inside with brake cleaner to remove the carbon buildup. The valve section rotates so be sure to turn it while cleaning with say a small ***** driver. Do not adjust or remove the top portion of the unit.
