Bigger tires ( greater footprint) are going to have that effect.
I just went thru this. I replaced every component, except the steering shafts. I wore the ball socket out on the intermediate shaft last rip out, and still need a replacement.
A weak pump can also contribute. One of those contributions can be from overheated fluids broken down, another would be the pump fins have worn, reducing flow, or a combo of both.
Blocked lines due to internal delamination of the old lines, can send bits of rubber to small ports and cause weak flow. I found this to be true inside the cooler tubes.
TRE's being too tight at the knuckle can cause a slow return to center, or non existent return. Use Factory Trq specs.
Then the big one.... The Rack itself. Internal damages can't be seen. Hard to diag this unit. Most give when the rams get worn, and leak fluids past the seals, drain out, and gears break. Bad fluids can be a cause, rubber bits from lines, and also lack of dust boots allow silt to ride the shafts into the unit as they abrade the seals, and shafts.
Then there is the not so obvious things, like the steering shafts binding. Main wheel shaft, and intermediate. Bolts under the dash can vibrate loose, and cause bind. Bearings can be worn.
Let me tell you, this was not a fun one for me, to figure out, and was extremely costly. Hope it's something simple for you!
