Well i have a 95 thunderbird with the 4.6. I have been noticing clunking and grinding throughout the front suspension. Took it over to the mechanic and they found that 2 lower and one upper ball joints that need replacing, control arms, driver side wheel bearing, and rear shocks. They quoted it about $1300 for all of the parts and labor. Now my question is should i even keep the car anymore? The car has 113K miles and i can see a new trans or trans overhaul in the near future with a new TC. I'm pretty sure the IRS bushings have been clunking since i got the car. Would it be even worth fixing knowing that i might need another $1000 worth of work in the near future?
