My 86 is supposedly on TRD struts in the back and it happens to lean on the rear drivers side pretty decently. I had my suspension checked out by Les Schwab and they said everything seemed fine. I was wondering if the strut was actually blown or leaking, or if for some reason was normal.

My Hachi was gangsta-leaning on the drivers side rear too.
After I replaced the shocks on all four sides, no more gangsta-lean.

Shocks shouldnt alter ride height. Not to say that they cant, im saying that they shouldnt. Checking for a blown shock is relatively easy- Especially rears on the rolla. Since you can see them quite easily, a visual is 9 times out of 10 a good indication. Inspect it, if you find oil- shes blown. Dont see oil but still SUSPECT its blown? Push down on that corner, holding it at the bottom, and then release it up as quickly as you can. A blown shock will take a moment to "settle", and will bounce up/down for awhile as the energy from the spring dissipates. A healthy shock (or dampner- a much more accurate name ) will do its job and absorb the springs energy, making the car "settle" right away.
