did you ever have the rear springs replaced as part of the Toyota recall? I have a 97 T4R SR5 & the springs were replaced as part of a recall. I am not sure if the 95 models were part of that, but it does not hurt to check. Just contact your local dealer & bring your truck in to the service department. They have a national database that will tell them if you ever had them replaced as part of the recall.
Could be an easy way to get some new rear springs for free.
