Bornindesert Posted February 19, 2013 Share Posted February 19, 2013 Posting a couple of suspension related questions - looking for a good source of OEM style UCA fasteners... When I broke down my stock D30 front axle and front suspension, two of the fasteners for the UCA's had mashed threads. I'd like to replace them with metric or OEM style bolts. They are a custom headed internal TORX metric bolt with a locking washer nut. Generally, I'm reusing any OEM bolt that cleans up when I install the lift, reusing the locking nuts that came off it. First question, I think the two damaged bolts came from the UCA to Axle bushing connection (didn't tag them). The UCA to frame bolts (or, the two other bolts) were metric washer hex bolt and locking washer nut. So, does that special bolt go on the frame end or axle end of the UCA? Second question: What's everyone using for sources of the OEM bolts for UCA's and LCA's? If not OEM, a good quality metric bolt, with washers, with nylon lock nuts? thanks!

Alexia Posted February 20, 2013 Share Posted February 20, 2013 I went to Lowes with a list of all the stock bolt specifications and put together a complete set for about $40. All of them are class 10.9. Going longer than the listed size is fine and is some cases for me I need an extra 5mm to 10mm of extra length to get proper thread engagement. If you can not find class 10.9 metric bolts then they are substitutes. A grade 8 9/16" bolt is 0.011" larger than 14mm and likely the holes are worn enough they will slide right into place. A 10mm replacement is a little harder since the same or larger size at 7/16" is 0.043" larger. Those would require enlarging the holes. UCA at frame: M10x1.50x85 UCA at axle: M10x1.50x?? - Length is not listed on my sheet, but it should be the same as at the frame. LCA at frame: M14x2.00x110 LCA at axle: M14x2.00x110 Link to comment Share on other sites More sharing options...
