thanks just what I was looking forRigidhitch.com is where I got mine. They are the same size as yours. They were 5-6 dollars each. Iboats.com doesnt have them. I had already checked. If mentioning the website is a violation please delete. No wrongdoing intended.
Generally the sleeves you get from an auto parts store are made out of metal only .011" thick. Way to thin for his requirements. Also if your axle is the "sure lube" type you will need to drill the grease holes in it.Take the part number from your seal, and go to Napa Auto Parts. They should be able to help you.
