@capsat thanks heaps for replying, glad to see such prompt response.
Will give you a little history about the vehicle, actually she had been parked for quite some time i'm assuming about 2-3 years, the last owner was a newbie interms of 4x4 vehicles and kept driving it in 4L till the rear differential worn out, it sounds funny but he thought the vehicle had both auto and manual gears so i'm not sure how many k's he's done with 4L engaged all along. Once that was done and dusted, he parked the vehicle and never bothered to repair or replace it. Anyhow currently the ODO sits somewhere around 3300K's. I know its a lot of mileage (flip side, the meter is not reversed/ tempered and the entire vehicle was in stock condition inside out). Since I got the vehicle I got the diff replaced from "shershah" karachi, the bushes were worn out too and the vehicle would wobble all around the place so I got that replaced as well. After a few days the alternator stopped working because the dude replaced the battery with a smaller sized battery. Anyways got that fixed too and was now all of a sudden the brake master cylinder gave up on me, though its a minor issue but will have to wait to get it fixed after the lockdown. Coming back to the maintenance, well the way she rides its less likely to say that she had been abused, the engine and suspension are in top notch condition, slight jerk in the transmission though while downshifting which i'm assuming is either gear or engine mounts that needs replacement but no lag in terms of shifting and the transmission oil isn't burnt or stinky, its still pinkish. Next thing i will be doing is getting a proper tune with all the liquids flushed, filters and plugs replaced along with cat clean. Hopefully this will help increase the mileage a bit.
