Sounds more like you need a serious front end overhaul. Ball joints, control arms, tie rods.....etc.
Shocks typically don't cause wobble. Unbalanced wheel cause vibration, not wobble. Worn front suspension parts are prime candidates to cause wobble.
You are driving a Gen 1 with a significant number of miles. Parts will wear out to get loose causing wobble.
Suggest to visit a shop that specializes in front suspension. Have them inspect and quote the work. Then make decisions. Don't fire the part cannon without a target.
i did visit a local 4x4 suspension shop earlier this year to give it a lookover
paid good money to have them tell me i needed new shocks in back (Toyota shocks were a bit squishy) new Bilstein 5100 in front (because those were leaking) and new sway bar links (rubber was cracked from age) the estimate i recall was over 1000$ for just those 3 items
my nephew and i did the front parts with the Monroe's, MOOG sway bar links and i recently put KYB on the rear. nothing much changed after all of that
i shall beat that dead horst UNTIL there is no horse left... because it TRULY pissed me off the big time
after the serious misdiagnosis by a Toyota pro last year of this weird vibe and rattle that would pop up now and then for 2yrs somewhere in the engine to cab area
I am highly skeptical of any of these places that claim to have the proper training and knowledge. I was not prepared for that clutch throwout bearing to breakout right into the moving fan that could've very well cost more than 1000$ in parts if that 'bearing' would've broken the clipped fan, sliced the belts, the radiator and shroud possibly leaving me stranded out in the nowhere country.
and had i not checked the oil level that day the bearing broke and noticed the charred up fan blade and did a visual inspection to see what was clipping it I may have destroyed the engine by running it unbalanced
I am trying to budget all of this around the looming needed clutch job, the t.o. bearing that broke is on its last legs and feeling very grabby sometimes
trying to see what maybe in my wheelhouse and not take months to do because the car is down for maintenance still
the current diagnostic/repair that is up next is the cold-weather noise that takes 15 minutes to disappear where i cannot safely drive the truck over 20mph when its below freezing for that 15 minutes of warmup time. I am not readily sure how much its going to cost to actually fix that issue LOL
