He died under suspicious circumstances before his father, paving the way for Trailokya's young son Prithvi to ascend the throne.

Crown Prince Trailokya, upon reaching his maturity[clarification needed] in 1875, decided to regain the royal prerogatives that his father had lost in 1856.

After Jung Bahadur died in Patherghatta, his youngest brother Dhir Shamsher spread the news that Jung Bahadur had not died, but was only critically ill. As Crown Prince Trailokya and Jagat Jang rushed to Patharghat, Dhir Shamsher compelled King Surendra to appoint Ranodip Singh Kunwar as the next prime minister, as per the laws of succession.

Crown Prince Trailokya died in 1878 under suspicious circumstances, after which his son Prithivi Bir ascended the throne.

The Crown Prince's Sahebju children continued to live in their areas or dukedoms with full state benefits and were free to occasionally travel to their Hanuman Dhoka Royal Palace residence in Kathmandu.
