Hi,
We recently purchased an immaculate 2004 Mobile Suite, so I have been reading the forums about them. Thankfully, this lead me to the plastic blocks in the bedroom slide. They were intact but both were cracked. I removed them and duplicated them with UHMW. My next fear is the wheels and tires. The trailer tows excellent and I checked all the axle and shock hangar welds they all look great. The wheels are chrome steel wheels (couldn't find a brand name but they are made in Korea) And the tires are new Goodyear G614 load range G. For those of you that have changed these older units whith leaf spring axles to 17.5" wheels and tires. Where did you get them? How did you determine which wheels would fit? My axles appear to have a 4.750 Hub Pilot and 9/16 studs. Any help would be appreciated.
Thanks,
Max
