hello & welcome. I use to be like you just change the bushings & ball joint. after doing this many times IMO get a control arm off ebay & be done w/ the job in 1 hr or less. well good luck, 
I think Helm makes a manual, but it's pretty expensive. I am not sure how applicable it would be to your car though, since it would have many things which are specific to the India market.Thanks Eddie. And Boston boy I will definitely be doing the bush change. I don't have the repair manual though I guess I will have to figure it out. Is there a diesel specific repair manual in existence?
I'd get under there and look for part numbers/markingsI am trying to figure out which automatic transmission I have though. It's a six speed. But I am not sure if it's the 6t40 or 6t45 or some other variant. Anyway to figure that out?
