So we have a leak of our power steering fluid. Turns out there is a crack in the reservoir. Is 130 Usd fair ?

 

sounds high to me, just get another pump at salvage yard $25 or $50 at the most,
You can change out just the reservoir...

 

You're definitely lucky if it's only the reservoir. If it were the gear/bearing/seal, then it gets messy.

 

I had a hell of a time trying to get the reservoir attached on my 00 TJ. If I ever do a PS pump again I'm not fooling around with trying to do the pump and reservoir separately, I'll replace the whole pump with a new reservoir.

 

never tried it myself... but honestly did sound like a bit of a PITA. lol

 

I have done it both ways. If you have the money, definitely less time to replace the entire unit. If you want to save some money, it's really not that bad to replace just the reservoir. There is a youtube video that covers it pretty much exactly:
The problem I have had is being patient enough to not break the reservoir where the return line comes back. Save yourself some headache and use a knife to cut the line lengthwise where it attaches to the reservoir. I tried on two units to twist the tube off. Broke the reservoir both times with the tube fused to the plastic. After that, I cut the tube and was able to separate it. Easier to get new tubing than to replace the reservoir.
