TEREX SKL834 (Schaeff - TEREX) Rear End clunking, Anyone have manual or advice? Also

New to Forum gents, We just picked up a terex 834 and it has a clunking sound in the rear end as well really wont move front or rear very well. It also has some obvious electrical issues.

Were here in the Metro Detroit area. Any one have a manual for the little girl? I think were close on the wiring but now the clunking started.

Any assistance will be greatly appreciated.

Thanks
