The LC is not a cheap vehicle to start with. Bear in mind you bought a used truck that depreciate over the years but new OE Toyota replacement parts are not. Replacing both CV Axles will set you back close to $2k with parts and labor including repacking bearings and replacing all the gaskets/seals with proper love and work done to your truck. If you are replacing all the front ends bushings and rear coil springs, the quote is about right. The 4 control arms bushings, stabilizer bushings, diff control arms and diff bushings is another $1k just for parts.
If you have the tools and time and willing to DIY then by all means DIY and just buy parts and save on labor. If you think LC parts and labor are high, wait til you own a BMW or RR.

I just did a bunch of work on a customer 99 LC with 164k miles, replacing both fronts cvs, all new gaskets and seals, replace bearings, needle bearing and bush, all new hardwares, new flanges, new flanges stud, washers, nuts, replace starter and connectors, replace ignition rod bracket, replace drive belt, replace diffs & transfer fluids, flush power steering and transmission, replace rack and pinion boot and clamp, replace lower ball joints and reboot upper ball joints, replace heater T, replace coolant temp sensor and connector, diagnose no start issue and replace transponder sensor, cooling system flush, grease driveline. We use only Genuine Toyota parts and repair to factory spec. $4700 repair.
Have another 2000 in right away doing similar and more work with only 109k miles. Goal is to restore it to mechanical sound condition, replacing parts that may fail due to age and also correcting previous shop mistake and bring the LC back to top condition to eliminate breakdown for the next 100k miles. We are replacing, cv axles, all seals/ gasket, starter, upgrade to 130amp 03+ alternator, radiator, heater T and all heater and radiator hoses, thermostat with gasket, fuel filter, air filter, cabin filter, valve cover gasket, spark plugs, ignition rod, pvc hoses, vacumn lines, all fluids. So the owner can take the truck to anywhere with not much worry about breaking down. This is the first phrase of the restoration, next we will be replacing the brake booster master cylinder assembly and main fusebox as well as all the control arms and diff bushings. Again only Genuine Toyota parts, no cheap aftermarket parts will be used to save few pennies down to the cotter pin. It is always fun to bring the cruiser back to its glory =)
