I just redid my springs and ubolts... have about $125 into the job.
Visit eastern marine's website - they are up in Newark, DE near 896 and 95 about 1 1/2 hr from you.

Buy new spring set (pair) ubolts, and bolts for springs.
Get a new cutting disk for your 4 1/2 grinder and cut all the old bolt off ... oh yeah take the boat off the trailer - it will shorten the job by about 5 days !!!
I did my trailer in my garage in November - 3 hrs Sat and 2 hrs Sunday - hardest part is cuting off the old sheeet.
It is a dirty greasy job - at this time of year do it inside if possible.
But before you go thru the trouble and expense - make sure the rest of the trailer is worth it - if frame, axle and cross memebers etc. are OK . If not (as mentioned in previous posts) look at a new one...
