The jeep is full time 4 wheel drive with the high low reduction so I put in low and tried going up the road again and as soon as one of the front wheels would break loose I get that loud bang so I backed down switched the E Drive on and tried again and install bangs as soon as I hit some loose gravel and the front wheel spins I took it to a shop had them change the seals to fix a leak and told them change the chain if need be brought them the TCL1 did the big circles and figure 8's in my field they said they changed the chain never had this problem before gonna try a new shop does anyone know where I can get the tool to measure the chain through the inspection hole

Anyone know where I can get a tool to check the chain tension on the quadra trac transfer case

I Don't know how would I check that front drive shaft

Just by checking rock auto it looks to be a double cardan.

Does the CJ have a 'Double Cardan joint' on the front driveshaft? I know my J-10 does and the 'centering yoke' can wear or break and cause quite a banging noise when under heavy load.

thank you so much I will find out how to check that shaft for wear when that bang occurs under load sounds like someone banging on the front Diff with a large hammer
